An earthquake of magnitude 3.0 occurred early morning on Monday 12 April 2021 at 6:47 am local time near Pýrgos, Ilia Prefecture, Western Greece, Greece, as reported by the National Observatory of Athens (NOA).
According to preliminary data, the quake was located at a shallow depth of 6.2 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 United States Geological Survey which listed the quake at magnitude 2.2. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 2.2.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Kardamas (pop. 1,100) located 13 miles from the epicenter, Pýrgos (pop. 22,400) 15 miles away, Amaliada (pop. 16,800) 15 miles away, Gastouni (pop. 8,100) 15 miles away, and Vartholomio (pop. 3,100) 16 miles away. In Epitalio (pop. 2,000, 18 miles away), Zakynthos (pop. 11,500, 18 miles away), Andravida (pop. 3,600, 19 miles away), and Lechaina (pop. 3,700, 21 miles away), the quake was probably not felt.

You can use your device location or the map to indicate where you were during the earthquake. Thank you!

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
