February 25, 2025, Greece has been experiencing significant seismic activity, especially around the Cyclades islands, including Santorini and Amorgos.

Greece is one of Europe's most earthquake-prone countries due to its location at the intersection of several tectonic plates, including the African Plate, the Eurasian Plate, and the Aegean Sea Plate. This complex tectonic setting results in frequent seismic activity, particularly along the Hellenic Arc in the south and fault zones across the mainland and islands.------ As of today, February 25, 2025, Greece has been experiencing significant seismic activity, especially around the Cyclades islands, including Santorini and Amorgos. In recent weeks, the region has seen an unusual swarm of earthquakes. Reports indicate that since late January 2025, thousands of quakes have occurred, with the University of Athens registering over 18,400 tremors near Santorini and surrounding areas by mid-February. Many of these have been relatively small, but several have exceeded magnitude 4, with the strongest reaching up to 5.3 so far this month. For example, a 5.3-magnitude quake struck near Santorini on February 10, felt as far away as Athens, followed by numerous aftershocks.------ This ongoing swarm has caused concern, leading to a state of emergency on Santorini, Ios, Amorgos, and Anafi. Schools have been closed, and thousands of residents and tourists have left Santorini due to the intensity and frequency of the tremors, which have triggered landslides and rockfalls. Greek authorities attribute the activity to tectonic plate movements rather than volcanic activity, despite Santorini’s location on the Hellenic Volcanic Arc. Seismologists note that while the frequency has slightly decreased recently, the situation remains unpredictable, and a larger quake hasn’t been ruled out.------ Historically, Greece has experienced powerful earthquakes. The strongest in recent decades was a magnitude 7.0 event on October 30, 2020, near Samos, about 268 km east of Athens. An even larger quake, magnitude 7.7, struck near Amorgos in 1956, causing significant damage and a tsunami. On average, Greece sees several hundred quakes of magnitude 4 or higher each year, with stronger events (magnitude 6 or above) occurring every couple of years.-------- The current activity around Santorini is considered unprecedented in its scale, though experts are still debating its exact cause—whether it’s purely tectonic or possibly linked to deeper crustal processes. For the latest updates, the situation continues to evolve, with monitoring ongoing to assess whether the swarm will escalate or subside.-------- https://x.com/i/grok?conversation=1894325318791450818
