Tidal variations and seismicity

Now you can made your own correlation between tidal forces and seismicity! 

-Colligate the change of gravity with seismicity, day by day, using the following graph. 

-See this daily variation of gravity analytically, by clicking on the date in the calendar of the present month, which is under the graph.

On the above graph:

• The curve shows the calculated medium daily tidal change of gravity. 

• Red solid bars show the recorded from NOA (National Geodynamic Institute of Athens) total daily seismic activity. (It is the total released energy in one day, expressed as one seism with magnitude on the ML scale).

According to Dr's Thanassoulas theory, big seisms occurring at the day where is the upper peak of the tidal curve, at the day of the lower peak of the tidal curve, plus or minus one day. Additionally, significant seisms occurring a few days afterwards significant electrical signals from the ground. Both parts of this theory were proved completely with the significant EQ's in the wide Greek area and the electrical signals that were recorded in my station during the last two years (2001 and 2002).
