The 5.1 magnitude temblor struck as Muslim Friday prayers were ending, causing the wall of one mosque to collapse in the town of Beni Ilman.
At least 43 people were hospitalized from injuries associated with the quake. Other buildings in Beni Ilman suffered damage or sustained cracks during the shaking.
The U.S. Geological Survey says the quake struck at 1:29 p.m. local time about 80 miles southeast of Algiers.
The relatively shallow depth of only 6 miles was responsible for the extent of the damage, according to seismologists.
Dozens of families near the epicenter were living in tents after losing their homes. Many said the government and aid agencies had not provided adequate relief supplies or support following the disaster, according to Ennahar Online.
Strong aftershocks rumbled across the region for the remainder of the weekend.
