Seismic Activity in the Aegean Sea Raises Volcano Eruption Concerns

A report highlights heightened seismic activity near Santorini, with over 900 earthquakes since January 28, raising concerns about potential volcanic eruptions and related tsunami risks to Türkiye. Geological factors influencing this situation are examined, emphasizing the need for ongoing observation. The public is urged to rely on official information rather than speculation.

A recent report by Türkiye’s Disaster and Emergency Management Authority (AFAD) and the Mineral Research and Exploration General Directorate (MTA) warns that ongoing seismic activity in the Aegean Sea poses a risk of triggering volcanic activity. Since January 28, seismic events near Santorini Island have surged, recording over 900 earthquakes by February 5, with the highest measuring 5.1. Most of these earthquakes have occurred in the Kolumbo volcano region, with depths ranging from 5 to 25 kilometers.

The report emphasizes concerns regarding potential hazards, including tsunamis that may impact Turkey, recalling that the last eruption of the Santorini volcano was in 1950, which generated a tsunami that reached Turkey’s coastline. It also highlights that volcanic activity can be influenced by tectonic movements and seismic activity related to magma chambers beneath the Earth’s surface. The significance of monitoring these earthquake swarms from geological and volcanic perspectives is stressed, even though a similar event in 2011-2012 did not result in volcanism.

Moreover, the ongoing seismic activity takes place within the South Aegean Volcanic Arc, which contains active volcanoes like Milos, Santorini, and Nisyros, all of which have erupted within the last 10,000 years. The Aegean Subduction Zone is crucial in this context, where the African Plate subducts under the Aegean-Anatolian Plate at a rate of 20 millimeters per year. Current developments show that shallow earthquakes are occurring, with no deeper seismic activity reported as yet.

The AFAD Earthquake Advisory Board, alongside Turkish scientists and researchers, is actively monitoring this seismic activity. The public is advised to refrain from following speculative social media posts regarding the situation and rely on official information provided by recognized institutions.

The Turkish agency’s report on the seismic activities near Santorini arrives amidst growing concerns about potential volcanic eruptions. Santorini, part of the South Aegean Volcanic Arc, has a history of eruptions and seismic events. Understanding the geological dynamics in this area, particularly the interactions between tectonic plates and magma, is essential for assessing the risks of future volcanic activity. Recent seismic swarms have prompted increased monitoring and attention to public safety in both Greece and neighboring Turkey.

The ongoing seismic activity in the Aegean Sea presents a potential risk for volcanic eruptions, particularly around Santorini and its associated underwater volcanoes. The situation is under continuous observation by Turkish authorities, with precautions against potential hazards, including tsunamis. Public awareness and reliance on official updates are crucial in managing this natural phenomenon. Historical precedents suggest that thorough monitoring is essential, as seismic activity does not always lead to volcanic eruptions.
