Santorini’s earthquake swarm has shown a steady decline, according to Greek scientists, easing fears after a month of heightened seismic activity. Over 20,000 tremors, some reaching magnitude 5.3, prompted evacuations across Santorini, Ios, Amorgos, and Anafi. Schools and businesses are reopening as thousands return, though officials urge caution amid lingering risks like rockfalls.
The University of Athens’ Interdisciplinary Committee for Risk and Crisis Management confirmed the trend:
“Seismic activity continues to show a gradual decline, both in terms of the daily number of recorded earthquakes and maximum magnitudes.”The swarm, linked to tectonic shifts and magma movements beneath the Aegean Sea, caused minor structural damage but no casualties.
Key updates include:
- Schools closed for four weeks are resuming classes.
- Over 20,000 earthquakes (magnitude 1+) recorded between Jan. 26 and Feb. 22.
- Thousands returned to Santorini since late February.
Santorini Mayor Nikos Zorzos emphasized the need for government support to address hazards like unstable hillslopes. “Repairing protective fencing and monitoring rockfalls are critical,” he stated. While the seismic activity has diminished, experts warn that volcanic regions like Santorini require continuous monitoring due to unpredictable magma dynamics.
This event underscores the delicate balance between natural beauty and geological risks in the Cyclades. Authorities remain on alert, combining scientific data with community preparedness to safeguard residents and tourists alike.
