The earthquakes occur in the same focal area, mainly southwest of Anydros, without any new microearthquake outbreak observed since February 15

Newsroom February 24 06:30

Over 23,500 earthquakes have been recorded since the onset of seismic activity in the Santorini-Amorgos region from January 26 to February 22, 2025, according to the Interdisciplinary Committee for Risk and Crisis Management of the ECPA.

At the same time, as highlighted, seismicity continues to show a gradual decline, both in terms of the daily number of earthquakes and maximum magnitude. It continues to occur in the same focal area, mainly southwest of Anydros, with no new microseismic upsurge observed since February 15.

Distribution map of earthquakes in the Cyclades region (Santorini-Amorgos-Ios) recorded on February 20-22 (AI analysis) and February 23 (daily analysis) – The radius of the circles is proportional to the magnitude of the earthquake (top-right footnote), while the epicenters of earthquakes with magnitudes greater than or equal to 4.5 are marked with a star – The colouring corresponds to the focal depth, according to the colour scale (right)
