The AFAD report indicated, “This swarm of earthquakes has resulted in the largest tremor so far, measuring 4.8 on the Richter scale. The quakes have shown increased activity about 25 kilometres north-east of the island of Santorini, at depths ranging from 5 to 25 kilometres. The closest earthquake to the Turkish coast occurred 140 kilometres away.”

It was noted that a similar level of seismic activity was observed in the same region between 2011 and 2012, which lasted for 14 months, though it did not result in any volcanic activity.

Meanwhile, Greek sources reported that over 200 minor earthquakes had been detected in the Aegean Sea and surrounding islands. The strongest of these, measuring 4.6 in magnitude, occurred in the waters between Santorini and Amorgos on February 2 afternoon.

According to the Institute of Geodynamics - National Observatory of Athens (GEIN), a 4.2 magnitude tremor was recorded on February 3 at 7:10 AM local time (5:10 AM GMT), located to the north-west of the small island of Anafi, near Santorini.

Efthymios Lekkas, President of the Organization for Anti-Seismic Planning and Protection, spoke to public broadcaster ERT, stating that while there is a "slight possibility" of a tremor with a magnitude of 5.5, the risk of a quake above magnitude six has been ruled out.
