Seismic activity in the Santorini-Amorgos zone is gradually declining, according to the Seismology Laboratory of the National and Kapodistrian University of Athens (EKPA).
The daily number of earthquakes and their maximum magnitude have decreased. From February 20 to February 23, no earthquakes exceeding 4.0 on the Richter scale were recorded.
On February 20, over 270 tremors were recorded, with 17 measuring above 2.5 magnitude and none reaching 4.0.
The strongest quake that day, measuring 3.7, occurred at 10:09:53 UTC (12:09:53 local time on February 21). On February 21, more than 280 earthquakes were recorded, with 18 exceeding 2.5 magnitude and none reaching 4.0.
The strongest tremor, measuring 3.5, was recorded at 4:57:34 local time.
The following day, February 22, over 300 quakes were registered, with 12 above 2.5 magnitude and none at 4.0 or higher. The strongest quake that day, measuring 3.3, occurred at 2:54:27 p.m. local time.
As of February 23, 61 earthquakes have been recorded, none of which exceeded 4.0 magnitude. The strongest tremor, measuring 3.6, was recorded at 5:26:21 p.m. local time.
The seismic activity continues to occur in the same focal area, primarily southwest of Anydros, with no new microseismic surges observed since February 15, according to a statement from the Interdisciplinary Committee for Risk and Crisis Management at EKPA.
The data, analyzed without the use of machine learning methods, indicates a steady reduction in seismic intensity.
