Greek authorities have advised residents on the Aegean island of Santorini to shut schools on February 3, avoid two small ports, and refrain from gathering in indoor spaces following increased seismic activity in the area. A series of tremors, up to a 4.3 magnitude, were registered on January 31 and February 1 between Santorini and Amorgos.
The civil protection ministry stated that the activity was not linked to volcanic activity and was receding, but experts proposed precautionary measures including school closures. People were also urged to avoid the small port of Ammoudi and the harbour of Fira, which serves mainly cruise ships.
Earthquakes measuring between 2.8 and 4.5 struck the area on the morning of February 2, according to the Athens Geodynamic Institute, without causing damage. Greece, which sits on multiple fault lines, is often rattled by earthquakes.
Santorini, one of Greece’s top tourist destinations, was formed by one of the largest eruptions in history around 1600 BC. The last eruption in the area occurred in 1950.
