| Zusammenfassung |
In this paper a new research tool called FastBEE (Fast Estimation of
Expected Big Earthquake) is proposed, for the analysis of three basic
seismic parameters, (the number of earthquakes N, b-value, and the seismic
energy released in the form logE2/3), in order to examine their
spatio-temporal variation behavior. The developed research tool is suited to
analyze earthquake catalogs and it comprise new interactive visualization
techniques for the exploration of the results. The tool was tested in
several seismic active areas of the Hellenic territory and a case study of
its applicability is presented.
It is observed that the results of the seismicity parameters analysis show a
clear temporal fluctuation, with respect to their mean values. Such a
behavior can be interpreted as the result of the geodynamic process acting
in the region. In several cases the observed significant changes can be
related to strong earthquakes, so that they can be considered as precursor
indicating the preparation stage for an impending strong earthquake
activity. |
