A magnitude 4.7 earthquake near Argostoli, Kefallonia, Ionian Islands, Greece, was reported only 20 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a very shallow depth of 5. km beneath the epicenter early morning on Saturday, March 21st, 2026, at 1:31 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 Italy's National Institute of Geophysics and Volcanology (INGV) which listed the quake at magnitude 4.5. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 4.4, the German Research Centre for Geosciences (GFZ) at magnitude 4.4, the National Observatory of Athens (NOA) at magnitude 4.2, The Seismological Survey of Serbia (SSS) at magnitude 4.3, The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 4.2, and The Seismological Laboratory of the University of Athens (UOA) at magnitude 4.2.Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage. Moderate shaking probably occurred in Lixouri (pop. 3,800) located 6 km from the epicenter.In Argostoli (pop. 9,800) located 11 km from the epicenter, Faraklata (pop. 1,100) 12 km away, Valsamata (pop. 1000) 18 km away, and Sami (pop. 1,300) 22 km away, the quake should have been felt as light shaking.Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Preveza (pop. 17,300) located 84 km from the epicenter, Agrinio (pop. 46,900) 97 km away, Amaliada (pop. 16,800) 97 km away, and Pátrai (pop. 168,000) 117 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
