A shallow magnitude 3.7 earthquake was reported early evening near Patras, Achaea, Western Greece, Greece.
According to the National Observatory of Athens (NOA), the quake hit on Saturday, May 27th, 2023, at 6:49 pm local time at a shallow depth of 11.4 km. 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 citizen-seismograph network of RaspberryShake which listed the quake at magnitude 3.8.
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.
Weak shaking might have been felt in Spartorachi (pop. 30) located 2 km from the epicenter, Rio (pop. 4,700) 6 km away, Patras (pop. 168,000) 9 km away, Nafpaktos (pop. 13,400) 10 km away, Paralia (pop. 6,300) 15 km away, and Ovria (pop. 5,800) 16 km away.
