ATHENS

Seismic activity that started in early February, triggering tens of thousands of people to evacuate, is continuing to shake Greece’s Cyclades Islands, located in the southern Aegean.

Over 30 tremors, including one measuring 5.1 on the Richter scale, had been recorded by around midday Monday in the area primarily concentrated around the islands of Santorini, Amorgos, and Oia, said Greek daily To Vima.

Greece’s leading seismic and volcanic risk committees met to assess the ongoing tremors in the area, it said.

They cited both tectonic shifts and deeper magmatic processes as potential drivers of the activity.

The seismic activity appears to be subsiding, they said, with the Santorini Caldera remaining stable, but ground deformation in the wider region requires further monitoring.

Public buildings in affected areas have withstood the seismic forces well, the authorities said.
