Seismic Activity in Aegean Sea Raises Concerns of Volcanic Eruption
Turkish authorities report potential volcanic activity due to over 900 earthquakes in the Aegean Sea, particularly around Santorini, with the largest measuring 5.1 in magnitude. The Kolumbo volcano’s location raises concerns, and historical data indicates previous eruptions. Ongoing monitoring by AFAD is essential, as the region exhibits complex tectonic interactions.
The Turkish Disaster and Emergency Management Authority (AFAD) and the Mineral Research and Exploration General Directorate (MTA) have reported that continuing seismic activity in the Aegean Sea could potentially lead to volcanic eruptions. Their assessment highlighted over 900 earthquakes near Santorini Island since January 28, with the largest reaching a magnitude of 5.1, predominantly at depths between 5 and 25 kilometers.
The earthquakes are largely concentrated around the Kolumbo volcano, situated northeast of Santorini. AFAD noted that the nearest quake to Turkish shores occurred 140 kilometers away from Turkey’s coast. Historically, the Santorini volcanic complex erupted last in 1950, resulting in a tsunami impacting Turkish waters.
The assessment emphasizes the interplay of tectonic and seismic movements potentially triggering volcanic activity. It compares the current seismic swarms to similar events observed between 2011 and 2012, which did not lead to eruptions despite intensive activity. The report encourages ongoing monitoring of the situation in light of recent tremors.
Moreover, the South Aegean Volcanic Arc is known for its active volcanoes, including Milos, Santorini, and Nisyros. The region sits above the Aegean Subduction Zone, where the African Plate converges with the Aegean-Anatolian Plate at a rate of 20 millimeters annually, explaining the shallow nature of these earthquakes.
AFAD’s Earthquake Advisory Board, along with Turkish scientists, continues to observe seismic trends closely and urges the public to disregard unverified social media speculations about seismic events, directing them to rely on official information.
The Aegean Sea, particularly around Santorini, is geologically active, with a history of both earthquakes and volcanic eruptions. The region’s volcanic complexes are shaped by tectonic interactions between the African and Aegean plates. Earthquakes can signal potential volcanic activity, as crystallized magma may be involved, thus requiring careful scientific monitoring to assess risks effectively.
In conclusion, the seismic activity near Santorini poses potential risks of volcanic eruptions, akin to past events. The 900-plus earthquakes recorded signal heightened geological activity, necessitating strict observation by relevant authorities. The historical context of earthquakes and volcanic activity in the region underscores the importance of relying on reputable sources rather than speculative social media commentary.
