Multiple earthquakes continued to shake the Cyclades Monday morning.
The most significant tremor, a 5.1-magnitude earthquake, occurred at 09:49 am Greek time (EET), 20 km SSW of Arkesini, Amorgos, at a depth of 11.9 km. Another notable quake of 4.3 magnitude struck nearby just a few minutes before at 09:46.
At 01:08 this morning a quake Magnitude 4.5, struck 23 km SSW of Arkesini, Amorgos.
Other more moderate tremors included a 3.5-magnitude earthquake at 10:06, 49 km south of Akrotiri, Santorini, and a 3.1-magnitude event at 09:57, 26 km northeast of Oia.
In total, more than 30 earthquakes were recorded before 11am, primarily concentrated around Amorgos, Santorini, and Oia.
According to yesterday’s announcement by the Interdisciplinary Committee for Risk and Crisis Management on seismicity in the Cyclades region at the National University of Athens, from January 26 to February 14, they have recorded over 19,200 earthquakes.
On Sunday Greek Prime Minister Kyriakos Mitsotakis, in his weekly social media update, addressed the ongoing seismic activity near Santorini, calling it an “unprecedented phenomenon” with unpredictable fluctuations.
Also on Sunday Greece’s leading seismic and volcanic risk committees met to share latest assessment of the ongoing tremors near Anydro, between Santorini and Amorgos. They cited both tectonic shifts and deeper magmatic processes as potential drivers of the activity.
They stated that seismic activity appears to be subsiding, that the Santorini Caldera remains stable, but ground deformation in the wider region requires further monitoring, and that public buildings in affected areas have withstood the seismic forces well.
While no immediate volcanic activity is confirmed, precautionary measures remain in effect.
