Four earthquakes above 4.0 magnitude have struck the area between the islands of Santorini, Anafi and Amorgos in the past 12 hours, amid ongoing seismic activity that has rattled the region for two weeks.
At 1.54 p.m., a 4.0-magnitude earthquake struck, followed by another tremor at 1.59 p.m., measuring 4.3 magnitude. Both quakes had their epicenter 25 kilometers south-southwest of Amorgos, according to the National Observatory of Athens’ Geodynamic Institute.
A 4.1-magnitude quake was recorded at 11.02 a.m. Sunday, 26 kilometers northeast of Oia, Santorini, following another 4.1-magnitude tremor at 3.30 a.m. northwest of Anafi.
While scientists mostly attribute the activity to a seismic swarm, concerns remain over the potential for a larger earthquake. Authorities have ruled out volcanic activity at Santorini’s Nea Kameni or the underwater Kolumbo volcano.
Precautions include school closures on Santorini and nearby islands until February 14, traffic restrictions in landslide-prone areas, and emergency preparedness. Prime Minister Kyriakos Mitsotakis recently announced 3 million euros in funding for an evacuation route on Santorini.
