Just 8 minutes ago, a 3.6-magnitude earthquake struck near Irakleion, Heraklion, Crete, Greece. The tremor was recorded in the afternoon on Tuesday, October 21st, 2025, at 4:55 pm local time, at a very shallow depth of 5. km below the surface.
The event was filed by the National Observatory of Athens (NOA), the first seismological agency to report it.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.8.
