ACTIVE FAULT IN KHERRATA

Kherrata Fault, also called Kherrata fold-fault (Roth, 1950) is located in the mountains of Babors at Kherrata (NE Algeria), it marks the beginning of the plain. It is oriented NE-SW fault whith north dipping. This fracture between two topographically and geologically distinct regions, with the folded limestone north Babors and dumped in the south of the country where the marl hills Senonian is almost horizontal. According to Rothé (1950), this fault is responsible for the earthquake in 1949. Besides Kherrata. Gabert (1984) believed that the creation of volumes in the mountainous region Kherrata is recent and may still be in progress during seismic events. Indeed, the Babors region has experienced several earthquakes in recent decades, the latest being that of Laalam in 2006. The geological and tectonic study in this work has shown evidences of neotectonic activity on this fault and Geophysical Electric Imaging contributed greatly to the knowledge of this active fault geometry. This work will further the understanding of seismotectonic model of North Algeria.
