A very strong 6.0 earthquake hit off the coast of Bejaia, Algeria in the middle of the night on Thursday, 18 March 2021, at 1:04 am local time. The epicenter was located at 18 km north of the Mediterranean Port City, and at the shallow depth of 10 km.
Within minutes after the quake, we received numerous user reports describing moderate to strong shaking. Our monitoring service also received reports of feeling the quake up to a distance of 250 km from the epicenter. The shaking reached the towns of Batna, Algeria, and Annaba.
In the photos above sent by one of our users, they show the damage caused by the quake.

The General Directorate Of Algerian Civil Protection reported panic in the streets as the residents fled from their homes. Some damage was reported including cracked residential halls and partially collapsed, old, unoccupied buildings. No injuries or casualties have been reported.
In video compilations posted on Youtube and other social media platforms (such as this one), panic stricken residents of Bejaia, Algeria were shown. Several destroyed or partially collapsed buildings were also captured. Residents were also shown clearing the streets of any debris from damaged walls. This is to remove any objects that may impede emergency operations or cause heavy traffic.

Within the past 24 hours, our monitoring service was able to detect at least 15 aftershocks from this quake. Almost all of these were felt and recorded magnitudes of 3.9 up to 5.1. The strongest aftershock hit just a few minutes after the main 6.0 quake.
The last strong earthquake that hit Algeria was the May 2003 Boumerdes Earthquake which recorded a magnitude of 6.8. It was reported to have recorded an intensity of X. The quake left over 2,000 casualties, 10,000 injuries, and 200,000 people homeless. Along with this, 10,000 buildings got destroyed or partially collapsed. The event was also able to produce localized tsunamis along the coastal areas of Northern Algeria.

Magnitude 5.8 earthquake strikes near Béjaïa, Algeria
5.8 quake 18 Mar 1:04 am (GMT +1)
5.8 quake 18 Mar 1:04 am (GMT +1)
Algeria was shaken near Béjaïa, by an earthquake of magnitude 5.8 only 14 minutes ago, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Béjaïa, Algeria, early morning on Thursday 18 March 2021 at 1:04 am local time. 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 United States Geological Survey, which listed it as a magnitude 6.0 earthquake. Other agencies reporting the same quake include Italy's National Institute of Geophysics and Volcanology (INGV) at magnitude 6.2, the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.7, and Spain's Instituto Geográfico Nacional (IGN) at magnitude 5.8.
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 Béjaïa (pop. 164,100) located 21 km from the epicenter.
In El-Kseur (pop. 26,100) located 40 km from the epicenter, Colmar (pop. 25,800) 40 km away, Barbacha (pop. 32,000) 44 km away, el hed (pop. 31,900) 48 km away, Akbou (pop. 66,700) 78 km away, Setif (pop. 288,500) 83 km away, and El Eulma (pop. 128,400) 96 km away, the quake should have been felt as light shaking.
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.
