Magnitude 4.3 earthquake strikes near Reykjavik, Reykjavíkurborg, Capital Region, Iceland
4.3 quake 12.1 Km WNW of Surtsey, Iceland, 7 Mar 2021 2:01 am (GMT +0)
4.3 quake 12.1 Km WNW of Surtsey, Iceland, 7 Mar 2021 2:01 am (GMT +0)
An earthquake of magnitude 4.3 occurred early morning on Sunday 7 March 2021 at 2:01 am local time near Reykjavik, Reykjavíkurborg, Capital Region, Iceland, as reported by the Icelandic Met Office (IMO).
According to preliminary data, the quake was located at a very shallow depth of 1.1 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.4 earthquake.
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 Vestmannaeyjar (pop. 4,200) located 29 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Thorlakshofn (pop. 1,500) located 62 km from the epicenter, Hafnarfjordur (pop. 26,800) 96 km away, Hafnarfjörður (pop. 26,800) 96 km away, Garðabaer (pop. 11,400) 98 km away, Garðabær (pop. 11,400) 98 km away, Kopavogur (pop. 31,700) 100 km away, Mosfellsbaer (pop. 8,700) 100 km away, Mosfellsbær (pop. 8,700) 100 km away, and Reykjavik (pop. 118,900) 101 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.

Reykjavík 104 / Light shaking (MMI IV) / horizontal (sideways) swinging / 5-10 s : The pre-shake sound and frequency shift was different than the previous quakes: more of a drop vibration than a rumble.
