Ongoing Earthquake Activity in Santorini Raises Concerns

The seismic activity in Santorini continues to escalate, with seismologists reporting numerous tremors in the region. The most significant of these was a quake measuring 5.2 on the Richter scale, occurring northeast of the island. This recent tremor has been noted as the strongest since the onset of this earthquake series several weeks ago.

The tremors have been felt not only across Santorini but also throughout the Cyclades islands, on Crete, and even in higher floors of buildings in Athens, approximately 230 kilometers away. Fortunately, authorities have reported no damage resulting from the seismic events.

Experts in seismology are cautioning that a larger earthquake, potentially reaching a magnitude of 6, could still occur. They indicate that until such an event takes place, the majority of the seismic energy in the area will not be fully released. Some specialists suggest that the current swarm of earthquakes may persist for an extended period, gradually diminishing over time.

Another area of concern is the potential influence of these earthquakes on local volcanic activity. Santorini is home to a prominent volcanic crater, and there is also a significant underwater volcano known as Columbo located to the northeast of the island. This underwater volcano had previously caused severe damage in the eastern Mediterranean following an eruption in 1650.

As the seismic activity continues, many residents are feeling increased anxiety. Reports indicate that approximately two-thirds of the local population have evacuated the island. Families with children, as well as workers involved in winter repairs of hotels and guesthouses, are among those leaving.

The tourist population on Santorini and neighboring islands like Ios, Anafi, and Amorgos remains uncertain as many winter visitors are either independent travelers or homeowners utilizing vacation properties.

Authorities have not issued an all-clear, and residents are being regularly informed about safety protocols in the event of a stronger quake or a potential tsunami. It is advised to avoid beaches and harbors during this period. Schools in the region have suspended classes, and emergency services, including civil protection units and additional medical personnel, have been dispatched to the island to assist.
