The situation on the Cyclades islands, which have been hit by countless earthquakes, remains tense. During the night, several earth tremors were recorded, the strongest northeast of Santorini with a magnitude of 5.2. According to the Geodynamic Institute of Athens, it was the strongest earthquake since the phenomenon began several weeks ago.

This quake was even felt on all the islands of the Cyclades group, on Crete and in the higher floors of buildings in Athens around 230 kilometers northwest of Santorini. However, no damage was reported, according to the authorities.

Is a stronger quake coming?

Most seismologists still believe that a larger quake is imminent, the intensity of which could reach magnitude 6. Only then can it be said that most of the seismic energy in the region has been discharged. Other experts believe that the so-called "earthquake swarm" will continue for a long time and slowly subside.

Influence of the quakes on the volcanoes unclear

It remains unclear to what extent this series of earthquakes could affect the two volcanoes in the region. In addition to the spectacular volcanic crater of Santorini, a similarly large volcano lies beneath the surface of the sea in the northeast of Santorini. The volcano known as "Columbo" caused severe damage in the eastern Mediterranean after an eruption in 1650.

Fear and flight: thousands leave the island

Meanwhile, the stress of the people on Santorini is increasing. No wonder if the earth has been shaking continuously for weeks, say seismologists. According to information from Greek radio, it is estimated that around two thirds of the island's inhabitants have left the island.

These are mainly families with children and workers who repair hotels and guesthouses during the winter and prepare them for the tourist season, according to Greek media reports. The number of tourists staying on the islands of Santorini, Ios, Anafi and Amorgos initially remained unclear. In winter, these islands are visited by people who either travel on their own or own a vacation home there.

Authorities remain vigilant and warn of tsunami risk

The authorities are not giving the all-clear. People are repeatedly being told what to do in the event of the feared stronger earthquake and possibly a subsequent tsunami. First and foremost, people should avoid going to the beaches or harbors at all costs. Schools in the region remain closed. Strong units of the civil service, fire department, civil protection and additional doctors, nurses and caregivers have also arrived on Santorini, reported Greek radio ERTnews.
