Seismic Activity in Aegean Sea May Signal Volcanic Threat, According to AFAD
Türkiye’s AFAD and MTA report over 900 earthquakes near Santorini, with potential implications for volcanic activity, particularly in the Kolumbo volcano region. Historical context emphasizes that increased seismicity requires careful monitoring, though similar past events did not lead to eruptions. The region’s geological complexity necessitates a reliance on official information to understand the risks involved.
A recent report from Türkiye’s Disaster and Emergency Management Authority (AFAD) and the General Directorate of Mineral Research and Exploration (MTA) indicates that ongoing seismic activity in the Aegean Sea could potentially trigger volcanic activity. As of February 5, over 900 earthquakes have been recorded near Santorini Island, with the largest reaching a magnitude of 5.1. These quakes are predominantly located northeast of Santorini, at depths varying between 5 to 25 kilometers.
The report emphasizes that the earthquakes are occurring in the vicinity of the Kolumbo volcano, which features an underwater crater situated northeast of Santorini. Significant historical context highlights that the last eruption of the Santorini volcano occurred in 1950, which led to a tsunami impacting the Turkish shoreline.
AFAD and MTA stressed the importance of monitoring these earthquake swarms closely, noting, “There is a possibility that the ongoing seismic activity may lead to possible volcanic activity.” However, they referenced a similar series of seismic disturbances from 2011 to 2012 that did not culminate in an eruption. The situation underscores the intricacies of volcanic geology and the potential influences of factors such as magma interaction.
The South Aegean Volcanic Arc, where this seismic activity is centered, contains several active volcanoes, including Milos and Nisyros. The region is characterized by the Aegean Subduction Zone, where tectonic plates interact, enabling continued monitoring by Turkish scientists and the AFAD. Citizens are advised to rely solely on updates from authorized institutions rather than unverified social media speculations.
The Aegean Sea, particularly around Santorini Island, is an area of significant geological activity due to its location along tectonic plate boundaries. The Aegean-Anatolian and African plates interact in this region, creating a complex and dynamic environment prone to both earthquakes and volcanic eruptions. This zone has historical precedents of volcanic activity, with the last known eruption of Santorini occurring in the 20th century, prompting ongoing research and surveillance to manage potential risks to surrounding areas, including Türkiye.
In summary, the recent surge in seismic activity near Santorini Island presents a potential risk for volcanic activity. While historical data suggests that not all seismic activity leads to eruptions, continued monitoring is crucial to assessing any changes that may arise. Authorities urge the public to remain informed through official channels and exercise caution regarding speculative information from unofficial sources.
