A strong earthquake registered by the EMSC as M6.1 hit Crete, Greece, at 22:51 UTC on May 13, 2025 (00:51 local time, May 14) at a depth of 71 km (44 miles). USGS is reporting M6.0 at a depth of 74 km (46 miles).
Significant ground fissures have emerged in the village of Voutes, near Heraklion on the Greek island of Crete, damaging homes, roads, and public infrastructure. The cracks, first observed on April 27, 2025, prompted an emergency response and the evacuation of multiple residences.
Researchers at the 10th Delphi Economic Forum on April 13, 2025, revealed that the use of advanced machine learning technology enabled them to detect over 50 000 earthquakes in Santorini, some of which occurred before the intense earthquake swarm in February 2025. This early detection enhanced earthquake forecasting and improved warning procedures during the crisis.
Severe floods swept through the Greek holiday islands of Paros and Mykonos on Monday, March 31, 2025, as a powerful storm over the Aegean Sea passed over the islands. Travel bans were issued for both islands as crews worked to clear roads that were blocked by landslides and floodwaters. Schools remained closed on the islands through Tuesday, April 1, 2025.
Schools in Santorini, Ios, Anafi, and Amorgos will remain closed at least until February 21, 2025, as the Greek government prepares for another meeting to assess seismic risks in the Aegean Sea near Santorini. Over 1 300 earthquakes were recorded with a magnitude above 3.0 in the sea area near Anydros since the beginning of the month, with the strongest reaching M5.3. The government also announced plans to build an emergency escape port in Santorini in addition to the new port under development.
Ios became the fourth island in the Aegean to be placed under a state of emergency on February 15, following the trend set by Santorini on February 6, Amorgos on February 12, and Anafi on February 13, due to the ongoing seismic activity in the region since late January 2025. On January 18, two M5.1 quakes were registered between Santorini and Amorgos, shaking the area with enough intensity to be felt across multiple islands.
Heavy rainfall from Thursday through Friday, February 13 – 14, 2025, led to severe flooding and landslides across the island of Kefalonia, Greece. Rainfall totals exceeded 150 mm (5.90 inches) over two days, causing widespread damage.
