Seismic Activity and Tsunami Impact

In Greece, over 200 earthquakes have recently affected popular tourist islands like Santorini, Amorgos, Ios, and Anafi. The strongest quake reached a magnitude of 4.9. This seismic activity led to school closures and increased flights to help tourists leave. The region, part of the Hellenic Volcanic Arc, is prone to earthquakes.
