The purpose of this page is
to demonstrate that EQs do not occur randomly in space, as it is believed by the
majority of the seismologists, but occur over specific well-defined deep
large fracture zones in the crust, located very easily by gravimetry.
Although the latter has been
validated for the large EQs (see related page of
this web-site), it is still valid, to some extent, even for the small magnitude EQs (down to 3R).
In the following graphs data are
presented as follows:
Tidal gravity variation,
for the last 15 days, along with the corresponding seismicity.
Athens regional area map
for a radius of 170 Km from the station (ATH),
overlaid by :
1. the deep fracture zones of the crust.
2. the corresponding seismicity for
the last 15 days, as it has been detected and
calculated from the NOA.
3. seismic potential
(threshold level : Ms = 6R) calculated for the year 2010
