Subject: Explosion at Colima volcano
A strong explosion occurred yesterday (29 July 99) at 14:42 hrs (local time) at Colima volcano's crater. Mr. Jesus Mendez, who is the political
authority of La Yerbabuena village (8 km from the crater, ~195 inhabitants, the nearest community) informed via radio that the explosion
was clearly heard and seen from the village. He also estimated that the pyroclastic flows and rockfalls triggered by the explosion reached
approximately the same distances of those produced by the 17 July 1999 explosion: a maximum runout of 5- 5.5 km along La Lumbre gully (volcano's west flank). On the Cordoban barrancas (SW flank) the distal reachness of the pyroclastic flows was estimated by him in ~3-3.5 km from the crater. Following yerterday's explosion, a relatively intense ashfall occurred on La Yerbabuena, causing irritations on eyes among some villagers and visitors, but fortunatelly few minutes after the ashfall, volunteers of Pro
eccion Civil Colima (Cuauhtemoc County) arrived to the village to provide light surgery masks to the people, so the effects of the ashfall were substancially minimized. Before this explosion, policemen of Policia de Procuracion de Justicia de Colima who were at La Yerbabuena previously and during the explosion reported intense jet sounds at 12:40 and some rockfalls.
A very light ashfall was noticed at the city of Colima (32 km to the South of the crater), which started at 17:05 hrs and stopped at ~ 20:00 hrs. More intense ashfall was registered at some towns located on the S and SE sectors of the volcano (Queseria, 7,700 inhabitants, 14.5 km from the crater; Montitlan, more that 50 inhabitants, 12.2 km from the crater).
At 18:04 hrs a strong exhalation was ejected from the crater. The ash column, rose rapidly, and reached at least 5,500 m.a.s.l., which was
clearly seen from the city of Colima. The observers of Proteccion Civil Jalisco posted at their observatory (4,000 m.a.s.l.) on the W upper slopes of Nevado de Colima (5.7 km to the north of Colima volcano's crater) reported that they did not hear any explosion sound accompanying this exhalation. It looks that this exhalation was responsible of most ashfall registered yesterday at the city of Colima.

2:00 p.m. - September 12, 1999
Earthquake swarm and ground deformation event at Kilauea Volcano
Starting about 1:31 Sunday morning, September 12, a swarm of small
earthquakes and associated volcanic tremor began at Kilauea Volcano. The
swarm was concentrated along the east rift zone between Devil's Throat and
Mauna Ulu, but earthquakes eventually occurred in a broader area involving
the summit and south flank areas. The strongest part of the swarm lasted a
couple of hours, but earthquakes are continuing at the time of writing
(2:00 p.m., September 12), as is tremor from the summit caldera. Many of
the earthquakes were felt by residents of Mauna Loa Estates, Volcano, and
other nearby areas. Most of the earthquakes were shallow, within 2-3 miles
of the ground surface. The largest rift zone earthquake was approximately
magnitude 3.0. At 5:59 a.m. the largest earthquake in this episode
occurred beneath Kilauea's south flank, near Pu`u `O`o. This earthquake
was approximately magnitude 3.7, but final calculations have not yet been
made.
Accompanying the earthquake swarm was deflation of the summit area
and the east rift zone between the summit and Pu`u `O`o. The deflation,
detected by five electronic tiltmeters newly installed in this area, began
at about the same time as the earthquakes and tremor. We anticipate that
GPS data, currently being processed, will show substantial widening of the
rift zone.
The floor of crater in Pu`u `O`o collapsed and is now mostly
overed with rubble. Aerial views at about 11 a.m. showed only a tiny pad
of weakly spattering lava remaining in the crater.
The flow of lava through the tube to the coast was weak and
luggish when observed between 11 a.m. and noon. One small trickle was
entering the ocean at the bench, most of which had collapsed into the sea
since about 8 a.m. this morning. By 1:30 p.m., the steam plume had died,
and the eruption had entered into another pause, which likely will last
from a few days to several weeks.
------From the HVO Eruption Update Web Page today:
700 September 13, 1999.
The swarm of earthquakes reported in yesterday's update
(see below) has ended. Summit tilt is slowly recovering, but
ermanent tilt may have been induced at several other
stations. There is no significant tremor at Pu`u `O`o, and the
pause in the eruption continues.
1500 September 12, 1999.
swarm of small earthquakes and associated volcanic tremor
egan at Kilauea at 0131 September 12. The swarm was
oncentrated in a short segment of the upper east rift zone
between Devil's Throat and Mauna Ulu but eventually spread
across the summit and south flank. The main swarm lasted a
couple of hours, but earthquakes continued until at least
1500. Most of the earthquakes were shallow (1-5 km) and small
(magnitude less than 3); nonetheless, residents of the
Volcano area felt many earthquakes in the early Sunday hours.
One magnitude 3.7 earthquake at 0559 took place near Pu`u
`O`o at about 10 km depth. Sharp deflation of the summit and
east rift zone began at the time of the swarm. The rift zone
between the summit and Pu`u `O`o sagged and presumably spread
as magma intruded into the rift zone from beneath the
summit. The floor of the crater in Pu`u `O`o collapsed
several tens of meters and is now strewn with rubble, with
only a tiny pad of weakly spattering lava remaining. These
events initiated a pause in eruptive activity. By 1330 the
steam plume at the ocean entry had died. The bench began to
collapse between about 0800 and 0915 and was more than 80
percent gone by noon. By analogy to episode 54 in January
1997, today's events may initiate a pause that lasts several
days or more.

Kilauea Volcano Eruption Update
http://wwwhvo.wr.usgs.gov/
Another pause in episode 55 of the Pu`u `O`o - Kupaianaha eruption began at 0131 HST on the
morning of September 12. The supply of magma to Pu`u `O`o was interrupted in response to an
intrusion into the upper east rift zone in an area between Pauahi Crater and Mauna Ulu, based
on the location of small earthquakes and the pattern of ground tilt from several tiltmeters. About
8 hours after the start of the intrusion, the active lava bench on the south coast of Kilauea began
collapsing into the sea. Several small collapses were observed by scientists on September 12,
and by the evening of September 13, about 2 ha (5 acres) had been removed. The discharge of
lava into the sea stopped completely in the afternoon of September 13.
The intrusion began when three tiltmeters at the summit showed a downward tilt of the ground
(red line) toward the caldera. A swarm of small earthquakes along the upper rift zone
accompanied the ground deformation. The downward tilt indicates that magma was moving out
of the summit reservoir; data from two other tiltmeters on the east rift zone (east of Pauahi
Crater and just uprift from Pu`u `O`o) indicate the magma was moving into the rift zone. The
reversal of summit tilt about 4-6 hours later indicates when the intrusion stopped and magma
once again moved into the summit reservoir. An inspection on September 12 of the ground
above the intrusion did not reveal new ground cracks, which suggests the magma intusion did
not reach to within 1-2 km of the surface.
Much remains to be learned from this event. Leveling across the zone of intrusion on September
14 showed changes in elevations that provide clear evidence for a dike, but the size and depth
of the dike remain to be calculated. The onset of seismicity and tilting on September 12 was
abrupt and simultaneous to within the one-minute resolution of the tilt data, all along the rift zone
and the summit. This intriguing observation will be the source of considerable interpretative
effort by HVO staff and colleagues.

KILAUEA VOLCANO UPDATE
The lava pond in Pu`u `O`o remains active this
afternoon, and lava is oozing from the lava tube
system onto the surface between Pu`u `O`o and the
top of Pulama Pali. Tremor near the vent has increased
since yesterday.
1545 October 5, 1999
Observations yesterday and early this morning found no
active surface flows on Pulama pali or anywhere else in
the flow field. Consequently we are defining the period
from 2200 on October 3 to 0945 on October 5 as a pause.
During this time, tremor virtually ceased near Pu`u `O`o
and Kilauea's summit was showing slight swelling. However,
by 0945 today breakouts of lava were taking place from a
perched lava pond built above the lava tube about halfway
between Pu`u `O`o and the top of Pulama Pali. The pahoehoe
flows from the perched pond were small, but one entered a
kipuka just west of the pond and started fires. The surface
of Pu`u `O`o's lava lake this morning and early afternoon
was about 7 m below the terrace around the lake, which in
turn is about 50 m below the rim of the crater. A thin
crust caps the lake, broken only by three bubbling areas
and by sporadic crustal overturns. Tremor near Pu`u `O`o
is weak but distinctly higher than during the pause. Tilt
at Kilauea's summit is now flat.

This is not only true at the vent (making the spatter and cinder cone) but also at the ocean where the island increases its size as flows harden and extend beyond the existing shoreline. From time to time that also becomes unstable and acres of the stuff crash back into the sea - and on occasion has taken a visitor, who ignored the warning signs and ropes, with it. I am a great believer in what the ranger tell us is safe and what is not safe - they are not there to spoil our fun!

Rock Becomes a River
--by John Burnett, copyright 1999
Rock becomes a river underground,
superheated, supercharged,
answering only to Madame Pele.
Rock becomes a river underground,
spewing forth as a mighty geyser
leaping, reaching ever higher,
seeking to paint the sky
and cover its blue
with a brilliant hue of red.
Rock becomes a river underground,
trickling to the surface, then meandering
at a nearly apologetic pace
while coursing an interminable, inevitable,
inescapable path,
altering both topographic and human landscapes,
playing no favorites--
and exploding in a toxic haze
where the river meets the sea.

EPISODIC ACTIVITY AND LAVA OVERFLOWS FROM THE BOCCA
NUOVA OF ETNA CONTINUE. Repeated surges of lava have overflowed
the western rim of the Bocca Nuova, one of Etna's four summit craters,
since late 17 October, and spilled up to 4 km down the western flank of
the volcano. The overflows were caused by episodes of violent Strombolian
activity and lava fountaining at the crater which is completely filled; a
sizeable pyroclastic cone is growing in the western part of the Bocca
Nuova. Bombs are thrown over a large part of the summit area, making
visits to the scene of this exceptional activity highly dangerous. A detailed
report will be posted later today on the Etna News Page. - WORLDWIDE

MT ETNA ERUPTION UPDATE http://www.geo.mtu.edu/~boris/ETNA_news.html
21 October 1999 update. After continuing vigorously until the early morning of 20 October, the
activity from the eruptive vents in the W and NW part of the Bocca Nuova ceased, and the
overflow of lava through the notch (formed on 17 October) in the W crater rim stopped. Sometime
around dawn (0700 h local time=GMT+2), forceful expulsions of ash began from the SE vent in
the Bocca Nuova, which had shown little activity in the past week. Later that day weather
conditions deteriorated, and visual observations were rendered impossible. However, it was
stated this morning that the activity was at low levels throughout the day (communication from
Marco Fulle, Osservatorio Astronomico di Trieste, who presently stays at the Rifugio Sapienza
and received this information from forest guard personnel). This morning at 0300 h, intense
eruptive activity reportedly resumed, with renewed lava overflow from the Bocca Nuova onto the
W flank. As of the early afternoon of 21 October, bad weather is preventing visual observations.

The weather has been particularly bad lately which is why their Volcano Cam is not sending images - it seems like fog and low clouds are obscuring the eruption, but a glow is suffused throughout the entire area surrounding the mountain. It will be nice with the weather clears - though eruptions have been known to make their own weather systems. We'll just have to wait...I promise to post something as soon as it is available.

The Tambora Volcano, located in Indonesia, killed 92,000 people in 1815- the
most people ever killed by a volcano.
There are, at best guess, 1511 volcanoes that have erupted in the last 10,000 years.
The biggest volcano is the world is Mauna Loa in Hawaii (80,000 cubic kilometers).
The biggest volcano in our solar system is Olympus Mons on Mars (17 miles tall).
Ojos del Salado in Chile is the world's tallest volcano (22,589 ft or 6887m).
The largest eruption ever was Yellowstone 2.2 million years ago. The eruption
produced 2500 cubic kilometers of ash.
The youngest volcano is Paricutin in Mexico. It grew out of a cornfield in 1943 and erupted for 8-9 years.

Surtsey in Iceland is younger than Paricutin...And from Base to summit, Mauna Loa is the world's tallest volcano - 28,000' (8534.4 M) below sea level + almost 14,000' (4267 M) above sea level makes it 42,000' (12602 M) total.

Houses usually spontaneously combust when the lava approaches because of the intense heat...Then the lava paves over the entire place so nothing is left which is recognizable as having once been a home, yard, garden or proptecting wall around the place.

Mexican Volcano Shoots Smoke High Into The
Sky
MEXICO CITY (Reuters) - Mexico's Popocatepetl volcano sprang to life
Thursday morning after months of dormancy, sending smoke two miles into
the sky, officials said.
``Today, at 11:10 a.m. there was a moderately significant exhalation, lasting
19 minutes, that produced a smoke column of two to three kilometers in
height,'' the Interior Ministry said in a statement.
A series of tremors were also felt Wednesday at the volcano, 40 miles
southeast of Mexico City, from where 18 million residents can sometimes
see the volcano through the smog.
Ash was expected to rain on nearby communities. Mexico City airport was
placed on alert and some flights were delayed, airport officials said.
The government said there had been no significant change in activity at the
volcano, and that a yellow alert remained in place, prohibiting access within a
three-mile radius.
A yellow alert means that Popocatepetl, which last provoked safety warnings
in February, could erupt in weeks or months but probably no sooner.

On the best kids volcano site this letter and answer (by a Geologist I know personally!!!)http://volcano.und.nodak.edu/vwdocs/frequent_questions/grp13/question2153.html
dear srs: if the Popocatepetl volcano eruption could lava arrive to
Mexico City?
Alessandra
Hi Alessandra,
No, there won't be any lava from Popocatepetl getting to Mexico City. Popocatepetl does not produce very much lava and that
which it does produce is very viscous and slow-moving. Instead of flowing down the slopes it piles up into what is called a
dome. Popocatepetl is much more likely to produce explosive eruptions. These have already managed to spread ash all the
way to Mexico City, but the effects were not particularly serious. The biggest danger is from pyroclastic flows and lahars. These
are an immediate threat to the towns on the slopes of the volcano itself, and in the worst case scenario might affect Puebla, but
not Mexico City.
Sincerely,
Scott Rowland

The latest update on the Kilauea Eruption which began on January 4, 1983...
0645, January 5, 2000
Eruptive conditions are little changed from those of yester-
day. The ocean entries at the Lae`apuki bench continue to
be active. Lava continues to spread across the surface of
the west flow above and below Paliuli. The east arm of the
east flow remains active above Pulama pali.
This morning at 0550, at least four clusters of entry
points were feeding lava into the ocean from the front of
the Lae`apuki bench. There was, in addition, one sluggish
cascade over the old sea cliff near the west end of the new
bench.
Surface breakouts of pahoehoe toes continue just inland of
the bench. Much of the surface of the flow directly above
the old sea cliff has been renewed in the past several days.
Predawn glow this morning shows continued movement of the
reactivated part of the old easternmost flow. The location
of the glow suggests that the flow is active between about
1600 and 1100 feet elevation, above the top of Pulama
pali.
At least two small vents in the crater of Pu`u `O`o are
glowing this morning, but there is no flow or pond in the
crater. Seismic tremor near Pu`u `O`o is weak, and the tilt
at Kilauea summit is flat.

Spectacular eruption of Icelandic volcano
A volcano in Iceland has erupted, sending clouds of ash and smoke up to ten kilometres into the air.
The Hekla volcano -- one of the highest in Europe -- is in the remote south-west of the island and the authorities say there's no danger to local people but aircraft have been warned not to fly over the area.
Witnesses say the eruption is a magnificent spectacle with red-hot lava flowing down the snow-covered slopes of the volcano. In Icelandic mythology, Hekla was believed to be one of the gates to hell and a haunt of witches.

Iceland's volcanic spectacular
The volcano is an an uninhabited area Iceland's most active volcano, Mount Hekla, has erupted for the first time in almost 10 years, spewing columns of ash several kilometres into the sky.
Experts say the volcano poses no danger as it is situated in an uninhabited area about 120 km (75 miles) east of Reykjavik. The volcano, one of the highest in Europe, has erupted more than 20 times since the 11th century. In Icelandic folklore, it was believed to be one of the gates to purgatory.
Icelandic television said a lava flow from a fissure was estimated to be seven km (4.5 miles) long. Tousands of Icelanders have gone to witness the magnificent spectacle of red-hot lava and white snow. But the authorities warned drivers to beware of clouds of ash clogging up their engines. The 1,490-metre ( 4900-foot) volcano spewed ash all over Europe when it erupted last century. Seismologists say this latest incident resembles a 1991 eruption that lasted seven weeks.
No flights to or from Iceland had been cancelled. But despite the civil aviation authorities warning aircraft not to fly over the zone, a flying club announced that it was charging just over $100 for aerial tours of the volcano.

POWERFUL EXPLOSIONS AT MAYON; HEKLA ACTIVITY DIMINISHES
Over the past two days, Mayon unleashed its strongest explosions so far, terrifying tens of
thousands of people living in the surrounding areas, and sending glowing pyroclastics hundreds of
meters into the sky. Press photos show spectacular incandescent fountains illuminating the summit
area, and the upper flanks covered by glowing projectiles. According to news reports, the latest
activity was purely explosive, following several days of predominantly effusive activity. Philippine
volcanologists noted that each explosion appeared to be stronger than its predecessor, and that the
climax might yet come. So far, more than 50,000 people have been evacuated. Many left the areas
around the volcano voluntarily, being impressed by the latest series of strong explosions. Local
authorities asked thousands of residents, who had left areas not under threat, to return home. The
refugees have been accomodated in evacuation centers, and news reports lament the lack of food
and the threat of diseases. Warnings have also voiced about the danger of lahars, which might be
caused by rainfalls washing the new pyroclastics from the slopes of the volcano.

Babies Born As Volcano Erupts
TABACO, Philippines (Reuters) - Nine babies have been born in cramped
evacuation centers in the central Philippines where refugees from the wrath of
Mayon volcano have been sheltering for over a week, relief officials said on
Friday.
One of the new mothers, 35-year-old Asuncion Broncate, gave birth to her
seventh child early on Thursday in a room at a school in Tabaco town, which
was serving as a temporary shelter for 10 families.
``Despite our miserable condition it is hot, there is no electricity everything
went smoothly with the grace of God,'' Broncate told Reuters as she
breastfed her one-day-old baby boy at the Panal Bangkilingan Elementary
School.
Broncate said she gave birth without the help of a midwife or any trained help
at dawn on Thursday.
Other evacuees in the school, mostly farmers living on the slopes of the 2,460
meter (8,000 foot) volcano, later took the baby to a nearby hospital for an
examination, she said.
Veronica Madulid, a provincial disaster official, said eight other babies were
born earlier in the week at other centers around Mayon.
More than 65,000 people are currently housed in various evacuation centers
in Albay province since Mayon first began erupting on February 24.
The volcano killed 77 people in its last major eruption in 1993.

Thanks, Marcia!
Actually, I took that picture (along with *many* more) the day that David, Polly and I hiked out to the lava shield near Pu'u O'o. I think it was called "Kupaianaha" (not sure about the spelling). Marcia was with us the day before, when we hiked out to where the lava was flowing into the ocean.
That was quite a hike...it took most of the day! We scratched the paint on the sides of the rental car just getting to our starting point for the hike! I enjoyed the jiffy pop, popped on a hot vent!
The picture was just published in the "Dictionary of Volcanology and Seismology". It's a Spanish-to-English/English-to-Spanish translation dictionary of volcanology and seismology terms. The author, Ken Hornak, found
my web site last year, and asked permission to use the photo on the title page of the book. My sample copy of the book, signed by the author, came in the mail yesterday. It's a first for me!

If I remember correctly, the hike to where the lava flowed into the ocean was at night, and you joined us. The hike to the sea shield was a much longer hike, and we did that the next day. It took the whole day, and I was pretty tired by the end of it...and I was in better shape than I am now! :-)

Mayon Volcano Bulletin
12 March 2000
An ash puff with height of about one kilometer was observed at 0903H
yesterday. The ash column was drifted to the northwest direction. The ash
ejection was caused by water that comes in contact with the still hot lava
deposits at the summit. And at 1242H, another minor billowing ash was seen
descending the Bonga Gully due to the detachment of the new lava deposit at
the upper slope. The elutriated ash cloud drifted to the west-southwest by
the prevailing winds.
During the rest of the past observation period the volcano was relatively
quiet. This was manifested by faint crater glow at the tip of the cone and
weak to moderate emission of steam. Sulfur Dioxide (SO2) emission rate
decreased from the previous reading of 4,300 tonnes per day (t/d) to 4,000
t/d.
Seismic activity consisted of 5 low-frequency volcanic quakes and 7
episodes of short-duration tremors. Slight deflation of the volcano edifice
continued to be recorded by ground deformation measurements via precise
leveling.
PHIVOLCS considers the moderate seismic levels, deflation of the volcanic
cone, moderate steam ad SO2 outputs including crater glow to be part of the
volcanic processes involving the gradual return to quiet conditions. At
this stage, however, these parameters are still above normal repose levels
such that Alert Level 4 remains hoisted over the volcano.

This photo was taken some years ago when he and another geologist would spend several days in the field. They slept and stored all things under that rusty-roofed structure. It got covered by cinders regularly and had to be dug out. As I recall this place ( just in front of that vent - Pu'u O'o) was called Camp 7 and was covered entirely and permanently just as the 6 camps before them had been. The items on the tripods are lasers and reflectors with which they measure the deformation of the entire mountain of Kilauea.

STROMBOLI ON-LINE and ITALY'S VOLCANOES: THE CRADLE OF VOLCANOLOGY
proudly present:
Video clips of a paroxysmal eruptive episode at the Southeast Crater of
Mount Etna(Sicily), 15 February 2000, filmed by British film maker David
Bryant
A series of video clips in Quicktime format (.mov) showing the spectacular
eruptive episode at the Southeast Crater on Etna of 15 February 2000 has
been posted simultaneously at "Stromboli On-line" and "Italy's Volcanoes:
The Cradle of Volcanology". The videos, which range from 1.5 to 3.5 MB in
size, show all main stages of the spectacular event from the initial
Strombolian activity over the escalation and the rise of huge lava fountains
to the decline and end. We believe that this is extraordinary footage of a
volcanic eruption and are grateful to David Bryant for his availability to
share his material with volcano enthusiasts and volcanologists worldwide.
His full video will appear in a film about Mount Etna and Catania, which
will be broadcast later this year; information about this will be provided
timely to visitors of our web sites.
We have decided to post the video clips on both sites simultaneously,
because this will allow both U.S. and European visitors fast downloading. If
the connection to one of the sites is slow, you may thus switch to the other
site and see if this works faster. We also give tips about how to download
faster and without annoying ruptures of transmission, if you have a slow
line.
And this is where you will find the movie clips:

Usu Volcano, Japan crisis
***************************
Volcanic Advisory reports (nos. 1-7) on Usu Volcano, Hokkaido, Japan, were
issued from Japan Meteorological Agency (JMA) since 28 March. Number of
volcanic earthquakes around this volcano has increased since 8 a.m. (JST),
27 March; 16 times in 27 Mar. and 599 in 28 Mar. (including 68
felt-earthquakes) at the JMA site about 2 km south of the summit. At 07:08,
29 March, the quake of M3.4 occurred on this volcano. According to the Usu
Volcano Observatory, the hypocenter of the earthquakes locates on the
northern slope of the volcano. Neither volcanic tremor nor visible change
in fumarolic gas had not been observed by the 28 March night.
National Coordination Committee of Volcanic Eruption Prediction (Chaired by
Prof. Yoshiaki Ida, Univ. of Tokyo) commented a high possibility of
imminent eruption in this volcano in the 28 March evening. JMA is also
calling the local people's attention to mud flows triggered due to snow
melting by eruption. Hot spring resort locates on the northern foot of the
volcano, and about 1,600 guests stayed this night. However, more than 400
persons living around the volcano actively took refuge to safety places
like distant schools by the 28 March night, according to the attentions by
local governments.
Historical eruptions occurred in 1663, 1769, 1822, 1853, 1910, 1943-45
(Showa-shinzan lava dome eruption), and 1977-78. According to Akihiko
Tomiya, Geological Survey of Japan, precorsory phenomena of these
eruptions, mainly volcanic earthquake events, before eruptions lasted from
32 hours (1977-78) to 6 months (1943-45 eruption). Most of them began with
the Plinian phase, followed by pyroclastic flows and, then, dome growth.
The volume of tephra is 0.05 c.km for the 1943-45 eruption to 2.5 c.km for
the 1663 eruption. Information on Usu Volcano is in the site,
http://uvo.sci.hokudai.ac.jp/.

Japanese Volcano Eruption Forces 15,000 to Flee
DATE (Reuters) - Japan's snow-capped Mount Usu volcano erupted on
Friday, belching forth vast clouds of smoke and ash and forcing 15,000
people to flee their homes.
The 2,402-foot volcano, among Japan's most active, sent rocks hurtling into
the air as plumes of dark gray smoke streaked with blue lightning billowed
from the conical mountain.
Residents ran for cover, holding towels over their mouths as the smell of
sulfur pervaded the air.
Onlookers said they could taste grit from the eruption that hurled ash as high
as 8,850 feet into the sky. A carpet of ash coated cars and houses.
Tremors were jolting the hot spring resort area on the northern island of
Hokkaido as the eruption continued, Meteorological Agency official Manabu
Komiya told reporters.
Ash, volcanic rocks and mudslides had flowed toward the small town of Abuta
and the navy and the Coast Guard were deployed to evacuate the entire
population of some 2,000 from homes perched precariously between the
mountain and the sea.
Officials said four naval ships, five Coast Guard vessels and two military
helicopters had plucked residents to safety.
``Depending on developments, the eruption could cause even bigger damage,''
Prime Minister Keizo Obuchi said. ``The government will do whatever it can to
deal with the situation.''
Sailors on the naval vessels reported mudslides slipping down the
cone-shaped mountain toward Abuta, but navy officials said later these were
small.
Officials said there were no reports of casualties.
Mount Usu last erupted in 1978 after a series of earthquakes that gave birth
to a new and smaller volcano by its side. Mudslides triggered by that eruption
killed three people.
Troops had already helped to evacuate more than 15,000 people from towns
around the foot of the volcano and they were being housed in schools and
public halls.
Officials said they were establishing emergency post offices and banks to
allow residents easy access to their money.
FURTHER ERUPTIONS POSSIBLE
Government experts said another big explosion appeared unlikely but it could
take some time until the volcano settled down and more eruptions were
possible from new craters.
``The fact that the ash cloud rose so high suggests the force of the eruption
was strong. We can't dismiss the chance of other developments, like magma
moves,'' said Yoshiaki Ida, chairman of the government's volcano experts
panel.
Snow was falling heavily, further coating the slopes of the volcano still
shrouded by billowing smoke from explosions of gases from five craters on
the mountain's western slope.
Officials said initial assessments showed the eruption had not been as large
as first expected, but further blasts could not be ruled out. Thousands of
earthquakes had rumbled through the region since Sunday as the mountain
prepared to blow its top.
``Mount Usu has had seven significant eruptions that we know of, and at no
time has it ended quickly with only a small scale eruption, said Yoshio
Katsui, a professor at Hokkaido University.
The plume of smoke was not as large as the one spewed out by Mount Usu's
last eruption in 1978.
``It looks smaller than before,'' said one middle-aged woman watching the
smoke pillar from the shore of nearby Lake Toya.
Train services in the area had been disrupted, some flights had been diverted
and roads blocked off, officials said.
Officials warned residents to beware of mudslides amid predictions of heavy
rain later on Friday night because snow on the mountain, believed to be 11 to
31 inches thick, could melt rapidly.
Some 3,300 troops were providing food, water and blankets for evacuees.
Others were on reconnaissance missions around the mountain, including
some in helicopters.
A Hokkaido government official said 55,000 people living in five towns around
the foot of the mountain, including the hot spring resort town of Toya, could
be affected by an eruption.
Cabinet ministers, keen to appear on top of the situation after past criticism
for slow response to disasters, huddled at a crisis center at the prime
minister's residence to monitor events.
Officials warned there was a chance that an eruption at Mount Usu could
mimic the deadly flow of superheated gas and ash from Mount Fugen in
southern Japan in 1991, which killed 43 people.

Stromboli On Line: Etna Video and smoke rings
************************************************
May we bring to your attention the fact that now
STROMBOLI ON-LINE's 1999-Etna videocassette is available,
featuring South East Crater lava flows and hornito activity, and
Bocca Nuova paroxysm with the "small scale pyroclastic flow".
All footage was digitally recorded and processed (58min; VHS-PAL,
VHS-NTSC upon request); original sound only, no commentary.
Written explanations in German, English and Italian are added.
For further details please consult our website:
http://stromboli.net/shop/index-en.html
We would also like to ask if any of you are aware of publications
regarding «smoke rings». We were able, in February 2000, to document
exceptionally beautiful and long-lasting rings on Etna, and this arose
an incredible interest about their nature. We would be therefore glad
to be able to present a rather complete list of scientific references
regarding their origin. Etna's «ring world» can be seen at
