Translated title:
Assessment of the Seismic Hazard of Kefalonia and Ithaca for the period 1630-2014
Summary:
In this thesis, an attempt is made to assess the seismic hazard of the islands of
Kefalonia and Ithaca. Within the framework of the thesis, an aggregated
database of macroseismic intensities was formed by collecting all the available
recordings for the area of interest, as well as adding new ones, the degree of
intensity of which was estimated as part of this thesis. To calculate the seismic
hazard, the probabilistic approach was chosen, using the HAZAN program, which
is based on the extreme value theory. The results were displayed on maps using
QGIS software using the Inverse Distance Weighted interpolation technique.
Some of the conclusions drawn from the results are that the highest values of
maximum expected intensity appear in the wider areas of Lixouri and the greater
part of Paliki peninsula, as well as in Argostoli. Significant values of maximum
expected value of macroseismic intensity also appear in the northern parts of the
islands of Kefalonia and Ithaca, as well as in the southern and southeastern part
of Kefalonia. By comparing the results of the maximum expected values of
macroseismic intensities obtained from the seismic hazard analysis and the
maximum observed intensities based on the data available so far, it appears that
in some places highly overestimated seismic hazard values result. This fact
seems to be due to the lack of data for some places for significant historical
earthquakes.
