2022-04-16 17:00:39 UTC (2022-04-16) · approx. 7:00 PM UTC+2 local
On April 16, 2022 at 17:00 UTC, a magnitude 4.7 shallow crustal earthquake struck 37 km WSW of Kýthira, Greece, at a depth of 63.4 km and coordinates 36.0608°, 22.5925°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Greece, a region characterized by the Hellenic subduction zone, where the African Plate subducts northward beneath the Aegean at roughly 35 mm per year. The nearest mapped fault system is the Hellenic Trench. View all earthquakes in Greece.
