Seismic activity has been intense in recent hours, with dozens of small tremors recorded in Santorini, Amorgos, and the surrounding islands.

The most recent earthquake struck at 12:16 PM, registering a magnitude of 3.9 on the Richter scale. The tremor occurred 25 km north-northwest of Anafi, with a focal depth of 15 km.

Aftershocks have been frequent, with minor tremors ranging between 2 and 3 on the Richter scale.

Shortly after, another earthquake of 3.1 magnitude was recorded 18 km south-southeast of Arkesini, Amorgos.

Earlier on Saturday morning, weak tremors were reported within minutes of each other in Amorgos and Santorini.

What’s Happening with the Santorini Volcano?

A recent meeting held on Wednesday to discuss the volcanic activity in Santorini has sparked widespread discussion.

Experts largely downplay concerns, but seismic activity on the island persists. Speaking to state broadcaster ERT today, seismologist Gerasimos Papadopoulos assured the public that there is no cause for alarm.

“There have indeed been many earthquakes, especially over the past week. Since early January, but particularly this past week, we have recorded over 150 to 200 tremors. Only a few have occurred directly on the island of Santorini. Most of them are located northeast, about 10 to 30 kilometers away,” he stated.

“The important thing,” he added, “is that our analysis shows these are not volcanic earthquakes. In other words, they are not related to any underground volcanic processes beneath or around the volcano. These are purely tectonic quakes, the kind that could happen in any other part of the country.”

He emphasized that “of course, the authorities are right to take long-term precautionary measures in collaboration with scientific institutes to address potential volcanic risks.” However, he stressed that “both the seismic and, even more so, the volcanic risk remain negligible at this point.”

Papadopoulos concluded by stating, “Any eruptions expected in Santorini in the relatively near future will be of small scale. However, even those require preparation.”
