Earthquake Kefalonia: Minimal aftershocks worry residents

Residents in Kefalonia and Ithaca are concerned, with the “non-existent” up to date post-earthquake sequence, of the 4.8-magnitude earthquake that struck Sunday morning, focusing on the coastline between Poros and Sami.
 
According to seismology professor Athanasios Ganas, Director of Research at the Geodetic Institute of the National Observatory of Athens on the island, there have been five total aftershocks of 1.2 and 2.5 on the Richter scale. The earthquake in Kefalonia has seen five aftershocks. We have five seismographers on the island with the coverage being satisfactory. There are aftershocks, but not as many as one would expect, after a 4.8 magnitude earthquake. There is a weak post-seismic sequence, The opposite would be really worrying, “says the seismology professor, adding” The magnitude of the earthquakes recorded so far is about 1.2 to 2.5. We will wait to see how this happens, but in my opinion it is not worrying. “

According to Athanasios Ghana, an earthquake of 4.8 Richter based on statistical models should have given rise to even 4.5 Richter earthquakes. “A 4.8 earthquake is quite normal for the region of Kefalonia, and the crack which is activated is small, has a northwest-southeast direction and is at a depth of 13km. Eastern Kefalonia is a region of low seismicity and as a result there is little data regarding the most central areas of the island. “
