Early Monday morning, a 3.9-magnitude earthquake rattled the island of Amorgos, rekindling memories of the intense seismic activity that shook the region last February.
According to the Geodynamic Institute, the quake occurred at a depth of 10.8 km, with its epicenter located 14 km south-southwest of Arkesini, Amorgos.

The tremor, felt in both Amorgos and nearby Santorini, is linked to the same fault line responsible for February’s series of quakes. Efthymios Lekkas, president of the Earthquake Planning and Protection Organization (OASP), addressed the event on ERT, reassuring the public that such activity is expected in this seismically active region.
“This earthquake is not cause for concern,” Lekkas stated. “It’s part of the anticipated seismic pattern following February’s major activity. We expect quakes in the range of up to 5.0 magnitude in this area.”
