Significant magnitude 5.5 earthquake 34 km southwest of Mytilene, Greece
5.5 quake 1 Feb 10:35 am (GMT +2)
5.5 quake 1 Feb 10:35 am (GMT +2)
A shallow magnitude 5.5 earthquake was reported in the morning near Mytilene, Lesbos, North Aegean, Greece.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Monday 1 February 2021 at 10:35 am local time at a shallow depth of 10 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.
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 Agios Fokas (pop. 16) located 4 km from the epicenter, Polichnitos (pop. 2,700) 11 km away, and Agiasos (pop. 2,300) 19 km away.
In Skopelos (pop. 1,500) located 22 km from the epicenter, and Mytilene (pop. 28,300) 34 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Menemen (pop. 53,500) located 86 km from the epicenter, Bergama (pop. 57,200) 86 km away, Urla (pop. 45,200) 88 km away, and Burhaniye (pop. 38,100) 88 km away.
