    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.

  • Twin M5.1 earthquakes hit Santorini area, Ios becomes fourth island under state of emergency, Greece

    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.

  • Over 12 800 earthquakes hit Santorini-Amorgos zone in 10 days, Red Cross mobilizes to aid residents, Greece

    Over 12 800 earthquakes were recorded in the Santorini-Amorgos zone between February 1 and 10, 2025, with the strongest, an M5.3 event, registered at 22:16 LT (20:16 UTC) on February 10. In response, the Hellenic Red Cross (HRC) has deployed rescue teams, social workers, and psychologists to assist residents in the affected region.

  • Santorini under state of emergency after thousands of earthquakes, Greece

    ByRishika Yadav

    A state of emergency was declared for the Greek island of Santorini on February 6, 2025, due to significant seismic activity affecting the region over the past 10 days. The measure was announced by General Vasilis Papageorgiou, Civil Protection Secretary, and will remain in effect until March 3. The most powerful earthquake recorded so far, measuring 5.2 in magnitude, occurred on February 5. The continuous seismic activity has led to the evacuation of over 10 000 residents and workers from the island.

  • New study explains how Kolumbo volcano’s eruption led to destructive tsunami in 1650

    ByTW

    A study published in Nature on October 26, 2023, detailed the complex mechanisms behind the 1650 volcanic eruption of Kolumbo in the Aegean Sea, which led to a devastating tsunami. Using advanced 3D seismic data and numerical simulations, the researchers identified a sequence of a landslide followed by an explosive eruption as the key events.

  • Study reveals magma chamber at submarine Kolumbo volcano near Santorini, Greece poses a serious threat

    ByTW

    A new study published in AGU’s Geochemistry, Geophysics, Geosystems has revealed the existence of a magma chamber beneath the Kolumbo volcano, located near Santorini, Greece. Using a high-resolution technology called full-waveform inversion, the study found that the magma chamber poses a serious hazard as it could produce a highly explosive, tsunamigenic eruption in the near future.
