A magnitude 5.5 earthquake near Patras, Achaea, Western Greece, Greece, was reported only 6 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide.

The earthquake occurred at a shallow depth of 10 km beneath the epicenter early morning on Wednesday 17 February 2021 at 5:36 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.

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 Kastraki (pop. 910) located 7 km from the epicenter, Nafpaktos (pop. 13,400) 12 km away, and Aigio (pop. 20,400) 19 km away.

In Patras (pop. 168,000) located 26 km from the epicenter, and Agrinio (pop. 46,900) 55 km away, the quake should have been felt as light shaking.

Weak shaking might have been felt in Livadeia (pop. 21,500) located 79 km from the epicenter, Amaliada (pop. 16,800) 85 km away, Pýrgos (pop. 22,400) 92 km away, and Corinth (pop. 30,200) 99 km away.
