Seismic activity around the Greek island of Santorini intensified on February 9, with a 5.0 magnitude earthquake recorded at 21:05, 15 km southwest of Arkessini, Amorgos, according to SKAI. The tremor was the strongest since the 5.

The 1956 earthquake was a mainshock–aftershock sequence, with aftershocks lasting at least eight months after the mainshock. However, the current ongoing seismic activity near Santorini, at least as of February 7, features thousands of earthquakes, many with magnitudes ranging between 4.0 and 5.0.

The Greek island has a long history of earthquakes, but what is causing the recent series of quakes has scientists perplexed.
