Greek authorities have responded to an intensifying earthquake swarm near Santorini by closing schools and deploying emergency teams. The tremors, which began last week, have been growing in frequency and magnitude, raising concerns over potential stronger quakes in the region. While experts have ruled out immediate volcanic activity, the situation remains unpredictable due to the swarm’s unusual characteristics. The most powerful tremor recorded so far was a magnitude 5 earthquake, striking approximately 34 kilometres northeast of Santorini. The event occurred at 2:27 p.m. local time, as per the University of Athens’ earthquake monitoring system. Seismic Activity Driven by Faults, Not Volcanic Unrest According to reports, the ongoing tremors are attributed to fault movement rather than volcanic activity. Santorini, positioned on the Aegean Sea’s tectonic boundary, sits on the exposed section of a submerged volcano known as the Santorini caldera. David Pyle, Professor of Earth Sciences at the University of Oxford, told Live Science that the quakes are likely caused by fault lines shifting rather than magma activity. He described the swarm as unusual, highlighting the …
