It concerns the EQ of Dodecanese Islands area in South Aegean Sea, on 22nd January 2002 with a magnitude of 6.3R. Pre-earthquake electrical signals of 24-hour oscillation, that were recorded in my station in Volos, describe the events, a few days before it occur. We will see all the development of that phenomenon, from the period of calm, the preparation of the EQ, and anew calm. 

Important fact, is the successful prediction of that EQ, so much as for the big magnitude, as much as the time. Complete localization of epicenter is not possible with only one station that we have in our disposal. Localized only the azimuth direction from the station of measurements to the epicenter. 

THE EARTHQUAKE

Reported by USGS National Earthquake Information Center as:

2002/01/22  04:53:53 35.73N 26.70E 99.0 6.3 A  CRETE, GREECE

Also reported by the National Observatory of Athens (Institute of Geodynamics):

2002 JAN 22   04 53 54.3   35.56   26.73  104         6.1ML

 It was in about 600km distance SE of my station in Volos. The epicenter was in the Sea and in depth of about 100 Km, NW of island Karpathos and Eastern of Island Crete. There is the main fault between African and Eurasian plates. It was a very strong EQ that shakes Egypt, Turkey, Cyprus, and Greece. We had no serious damages in Greece. 

 SHORT- TERM EQ PREDICTION 

On 21st January you see in my daily updated graph:

It is recorded high amplitude of 17.1 mVolts. That means that:

A BIG EQ WILL BE OCCURRING IN A FEW DAYS IN GREECE.

  But WHEN we must expect the EQ?

We must see the tidal graph, in order to find WHEN. The EQ will be occurring within the 3 next most dangerous days on this graph. It was 21st January and as we can see on the graph, the next most dangerous days are 21st, 22nd and 23rd January.

This is absolutely correct as you see in the above graph.

ATTENTION: This graph means nothing without signals.

One other conclusion is that:

 THIS EQ WAS THE MAIN

because the signals are degreasing later.

Next question is WHERE?

On 20^th January, Dr’s Thanassoulas process and mine process too on my signals, it gives the azimuth direction to the South-East of my station, Here is the exactly azimuth direction and where finally occurred the EQ. 

The expected EQ must be occur ON OR NEAR THIS LINE.

Blue arrow on the above map, represents what azimuth direction we had calculated on 20^th January.

Unfortunately, we have only one station and we cannot find the epicenter on this line. We need two additional stations (at least), in order to calculate the position of the epicenter and the value of the magnitude too.
