Series of Strong Quakes Plagues Greek Island

Last week it was a 5.8 magnitude quake, and this week it was a 6.1. Both had similar epicenters, and both have caused damage to the Greek island of Cephalonia (Kefallonia). After the first quake, some geologists had speculated that it may not have been the main event, and after today's quake it would seem that they may be correct. Whether or not the 6.1 quake is the largest of the series remains to be seen. Many aftershocks are likely to follow.

There are no known volcanic centers in the area, according to any database, however the area does apparently lie on a subducting plate. The depth of 13km is at the right depth for magma intrusions, but this is likely not the case, and is probably purely tectonic.

"(Reuters) - A strong earthquake rattled the island of Cephalonia in western Greece early on Monday, the second tremor of this scale to hit the region in just over a week.

Τhere were no immediate reports of casualties.

The tremor measured 5.7 in magnitude and struck at 0308 GMT, according to the Athens Geodynamic Institute. The United States Geological Survey said the magnitude was 6.1.

Last week, a quake measuring 5.8 rocked the island, sending panicked residents fleeing from their homes and damaging some buildings.

"All evidence shows that this was the strongest quake to follow the main one, which struck last week," a senior official at the institute told Greek Skai TV.
