Just 7 minutes ago, a 4.2-magnitude earthquake struck near El Attaf, Ain Defla, Algeria. The tremor was recorded early morning on Saturday 31 July 2021 at 3:01 am local time, at a shallow depth of 10 km below the surface.
The event was filed by the European-Mediterranean Seismological Centre (EMSC), the first seismological agency to report it.
Our monitoring service identified a second report from the German Research Centre for Geosciences (GFZ) which listed the quake at magnitude 4.2 as well. A third agency, Spain's Instituto Geográfico Nacional (IGN), reported the same quake at magnitude 4.2.
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 El Abadia (pop. 28,700) located 4 km from the epicenter, and El Attaf (pop. 43,800) 6 km away, the quake should have been felt as light shaking.
Weak shaking might have been felt in Oued Fodda (pop. 44,500) located 13 km from the epicenter, Ain Defla (pop. 52,300) 29 km away, Orleansville (pop. 178,600) 30 km away, Ech Chettia (pop. 168,000) 35 km away, and Sidi Akkacha (pop. 26,600) 37 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Khemis Miliana (pop. 75,900) located 52 km from the epicenter.
