An earthquake of magnitude 3.3 occurred only 23 minutes ago 30 km northeast of Athens, Greece, the National Observatory of Athens (NOA) reported.
The quake hit at a very shallow depth of 5 km beneath the epicenter near Athens, Nomarchía Athínas, Attica, Greece, early morning on Saturday, May 13th, 2023, at 2:22 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from the Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC) which listed the quake at magnitude 3.2. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 3.3.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
