| Remarks | At least 628 people killed, 926 injured, 2,539 homes destroyed and more than 15,000 people homeless in the Al Hoceima-Imzourene-Beni Abdallah area, Morocco. Maximum intensity IX in the Imzourene-Ait Kamra area. Ground cracks and landslides were observed between Ajdir and Beni Abdallah and maximum horizontal acceleration of 0.24g was recorded near Imzourene. Felt from Tetouan to Nador and as far south as Fes. Felt (V) at Melilla and (III) in many parts of southern Spain from Algeciras to Roquetas de Mar. Felt (II) at Cordoba, Granada, Huelva, Jaen and Madrid. Also felt in Gibraltar. 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. 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.

NB:
The official magnitude for this earthquake is indicated at the top of this page.
This was the best available estimate of the earthquake's size,
at the time that this page was created. Other magnitudes associated
with web pages linked from here are those determined at various times
following the earthquake with different types of seismic data.
Although, given the data used, they are legitimate estimates of magnitude,
they are not considered the official magnitude.
The region name is an automatically generated name
from the Flinn-Engdahl (F-E) seismic and geographical regionalization scheme.
The boundaries of
these regions are defined at one-degree intervals and therefore differ from
irregular political boundaries.
