The 2004 Al Hoceima earthquake occurred on 24 February near the coast of northern Morocco. The earthquake registered 6.4 on the moment magnitude scale and had a maximum perceived intensity of IX (Violent) on the Mercalli Intensity Scale. At least 629 people were killed, 926 injured, 2,539 homes destroyed and more than 15,000 people were made homeless in the Al Hoceima-Imzourene-Beni Abdallah area.

Earthquake[edit]

The moment tensors and pattern of surface cracks indicate left-lateral strike-slip faulting on a buried NE-SW trending fault.

This quake occurred near the epicenter of the magnitude 6.0 Al Hoceima earthquake of May 26, 1994, that injured one person and caused significant damage to adobe buildings.[3]

Damage[edit]

Ground cracks and landslides were observed between Ajdir and Beni Abdallah and maximum peak ground acceleration of 0.24g was recorded near Imzourene.

Aftershocks[edit]

Several aftershocks killed at least three people and destroyed previously weakened buildings. This earthquake occurred near the eastern end of the Rif mountain belt, which is part of the diffuse boundary between the African and Eurasian plates.
