Turkish Agency Warns of Potential Volcanic Activity from Aegean Earthquakes

The Turkish authorities warn that over 900 earthquakes near Santorini may trigger volcanic activity. Most quakes, the strongest at 5.1, are located near the Kolumbo volcano, raising tsunami concerns for Türkiye. Monitoring is crucial as previous similar seismic activities did not lead to eruptions. Geological context and ongoing studies are essential for safety and preparedness.

The Turkish Disaster and Emergency Management Authority (AFAD) and the Mineral Research and Exploration General Directorate (MTA) have produced a report indicating that the ongoing seismic activity in the Aegean Sea near Santorini Island may trigger volcanic activity. As of February 5, over 900 earthquakes have been recorded since late January, with the strongest measuring 5.1, primarily occurring northeast of Santorini at depths ranging from 5 to 25 kilometers.

The report highlights the focus of these quakes within the Kolumbo volcanic region, situated approximately 6.5 kilometers northeast of Santorini Island, with the closest tremor to Turkey occurring 140 kilometers away. It raises concerns over potential tsunami impacts in Turkey, citing that the last significant volcanic eruption occurred in 1950, which generated a tsunami that reached Turkish shores.

Notably, the report expresses the importance of monitoring this seismic activity due to its potential to cause volcanism, influenced by tectonic movements or magma chamber dynamics. A previous sequence of seismic events in the same area from 2011-2012, although intense, did not lead to volcanic activity, indicating that while the risk exists, it is not guaranteed.

The report emphasizes that volcanic activity could vary based on geological factors such as eruption type, intensity, and magma-water interactions. It describes the ongoing seismic occurrences as part of the South Aegean Volcanic Arc, home to multiple active volcanoes historically erupting over the last 10,000 years.

Furthermore, the Aegean Subduction Zone plays a crucial role in this activity, where the African Plate subducts beneath the Aegean-Anatolian Plate at a rate of 20 millimeters annually. The earthquakes in Santorini occur at shallow depths and have not yet been linked to deeper seismic activities, warranting continued observation by scientific institutions, including the AFAD Earthquake Advisory Board, which advises against relying on unverified social media claims.

This report arises from the recent uptick in seismic activity around Santorini Island, known for its volcanic history. The heightened frequency of earthquakes, especially around the Kolumbo volcano, prompted concerns about potential volcanic eruptions and their implications for surrounding regions, including Türkiye. Historical data suggests that while seismic events can precede eruptions, they do not always lead to volcanic activity. Thus, ongoing monitoring by authoritative agencies is essential for public safety and awareness.

In conclusion, the report from AFAD and MTA highlights a significant increase in seismic activity in the Aegean Sea that may induce volcanic events. While potential dangers such as tsunamis could impact Türkiye, historical patterns indicate that not all seismic activities lead to eruptions. Continuous observation and reliance on credible information from scientific authorities are critical for understanding and mitigating risks associated with this geological phenomenon.
