A magnitude 4.2 earthquake near Reykjavik, Reykjavíkurborg, Capital Region, Iceland, was reported only 19 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 5.9 km beneath the epicenter in the afternoon on Thursday 4 March 2021 at 5:16 pm 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 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 Hveragerdi (pop. 2,300) located 17 km from the epicenter, Mosfellsbaer (pop. 8,700) 25 km away, Mosfellsbær (pop. 8,700) 25 km away, Selfoss (pop. 6,500) 26 km away, Reykjavik (pop. 118,900) 34 km away, Kopavogur (pop. 31,700) 35 km away, Garðabaer (pop. 11,400) 36 km away, Garðabær (pop. 11,400) 36 km away, Hafnarfjordur (pop. 26,800) 37 km away, and Hafnarfjörður (pop. 26,800) 37 km away.
