| Zusammenfassung |
A number of Seismic Electric signals data have been accumulated during the
last two decades that also includes the signals observed before the
magnitude 6 class earthquakes that occurred in Greece very recently i.e.,
the first two months of 2008.
Using all the available data we investigate whether a possible
interconnection exists between the lead time of Seismic Electric Signals and
the stress drop of subsequent earthquakes. We show that for "non
thrust" earthquakes a power law relation emerges with an exponent value
around 0.29, the possible physical meaning of which is discussed. This value
is very close to the range of critical exponents that govern the fracture
processes and is also comparable with the value of the slope, found much
earlier by the VAN group, in the linear relation between the logarithm of
the SES amplitude and the earthquake magnitude. |
