Skyros Island, Greece, EQ (26/7/2001, Ms = 6.1
The earthquake of
Skyros Island in Greece (26/7/2001, Ms = 6.1 R) was announced three
days before its occurrence in a meeting organized by the Bulgarian
Academy of Sciences, Sofia on 2001.
In this work a
review is made on the results of the methodologies which were used
for the analysis of the available data in order to utilize the
interest is the fact that the determined time of occurrence deviated
for less than an hour (actually it was 41 minutes) from the actual
occurrence time of the specific EQ. A similar example of another
large EQ (Kythira, Greece, Ms = 6.9R, 8th January, 2006) by using
the very same methodology deviated for 43 minutes only.
The rest of the
prognostic parameters: the epicenter location and the magnitude of
the Skyros EQ were utilized by manipulating the past seismic energy
release history of the regional seismogenic area and the observed
earth’s electric field which was recorded during the last 25 days,
before the occurrence of the large seismic event, by VOL earth’s
electric field monitoring site.
Indeed, the fact of the
presented methodology and the determined prognostic parameters, in
front of a seismological panel, was a very strong statement. The
panel reacted by smiling politely and the meeting went on normally
for a couple of days. On 2001/07/26 the specific EQ hit Skyros
Island occurred as it was expected. The seismological panel,
although it was largely surprised, produced, after my request,
a confirmation in written form.
It is concluded
that a short-term earthquake prediction can be utilized as a really
“short” one, once the available precursory data are processed with
the appropriate methodologies.
