A number of destructive earthquakes have occurred in the region of Algiers, the capital of Algeria. Two well-known historical earthquakes were recorded in 1365 and 1716 (Harbi et al., 2004). A more recent one, the 2003 Mw 6.9 Boumerdes earthquake (also called the Zemmouri earthquake), took place in the Boumerdes district (Fig. 1), about 50 km east of Algiers (Yelles-Chaouche et al., 2003). The Boumerdes earthquake occurred on a blind-thrust fault offshore from the Algerian coast. The rupture was along a northeast-southwest-striking fault plane, although the precise fault trace was unknown. During this earthquake, an average value of 55 cm of uplift of the shoreline was observed (Meghraoui et al., 2004), consistent with the thrust focal mechanism, at least in the high-slip region on the fault plane (Semmane et al., 2005).
More recently, in the same district (Boumerdes), an earthquake of moment magnitude Mw 4.1 (Md 4.3) occurred on 22 February 2014 at 20:30 local time, 12 km southeast of the epicenter of the 2003 Boumerdes earthquake, and at a depth of 7-11 km. The epicenter was located 5 km northeast of the central part of the town of Bordj-Menaïel and
