Contribution of the Algiers earthquake (Mw 6.8) of May 21, 2003 to the probabilistic seismic hazard values in Northern Algeria

On May 21, 2003, at 18:44 UTC (19:44 local time), a strong shallow earthquake with magnitude MW 6.8 caused severe damage in five wilayas (provinces) in the north central part of Algeria. The epicenter was located by the CRAAG offshore at (36.91°N, 3.58°E), 7 km to the north of Zemmouri, in the wilay...
