Abstract:
We present the Paliki, Kefalonia, Greece earthquakes of 1867 and 2014 in an effort to compare the effects and assign macroseismic intensities of earthquakes originating from the same seismogenic source. For the first event our sources are the three detailed field reports by Schmidt, Typaldos and Vergotis and four local newspapers. For the 2014 events (26 January and 3 February) the second-degree building inspections and the vulnerability categorization following the 2011 census, as well as ample photographic material and witness reports were used for intensity assignment. In both cases, 90% of the localities on the island were almost similarly affected by both earthquakes. Particularly, the studied earthquakes ruined or severely damaged the villages and towns in Paliki peninsula. We investigate the evolution, in terms of population and building activity, of these localities within the time span of 147 years between the two earthquakes, taking also into account the several significant earthquakes that occurred within this span. A total number of 65 (1867 event) and 97 (2014 events) intensity datapoints are collected from the island of Kefalonia. The macroseismic parameters of the historical event, when compared to the instrumental ones, show significant similarities.
