A magnitude 4.2 earthquake near Reykjavik, Reykjavíkurborg, Capital Region, Iceland, was reported only 16 minutes ago by the Icelandic Met Office (IMO), considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a very shallow depth of 5.4 km beneath the epicenter early morning on Saturday 3 April 2021 at 1:11 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 was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Grindavik (pop. 2,900) located 9 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Vogar (pop. 1000) located 13 km from the epicenter, Reykjanesbaer (pop. 2,000) 20 km away, Hafnarfjordur (pop. 26,800) 28 km away, Garðabaer (pop. 11,400) 30 km away, Kopavogur (pop. 31,700) 32 km away, Seltjarnarnes (pop. 4,300) 34 km away, and Reykjavik (pop. 118,900) 35 km away.
