Geological, geomorphological, and morphotectonic studies at the Gesher Benot Ya'aqov Acheulean site, Northern Jordan Valley, provide: 1) a unique opportunity to establish the ecological background of hominid behavior during the early stages of widespread human occupation; 2) crucial data for understanding the paleo-environment and the various processes that affected the area near the Gesher Benot Ya'aqov site; and 3) a basis for further comprehensive research in the region.

Quaternary tectonic activity near the Acheulean archeological site has produced a complex local setting that controls the surrounding landscape. Tectonic activity formed the Benot Ya'aqov embayment, which attracted hominids and a variety of other fauna. Sediments of the Benot Ya'akov formation deposited in the embayment facilitated excellent preservation of the remnants of Acheulean hominid activities and of abundant floral and faunal remains. The formation was subsequently affected by faulting and folding. Local uplift ended the deposition of lacustrine sediments in the embayment of Hula Valley Basin and caused erosion and vertical incision of the Jordan River that resulted in the capture of the Rosh Pinna River and the exposure of the Benot Ya'akov formation. These deposits are found in different structural positions along the north–south oriented morphotectonic embayment. The outcrops contain numerous archeological sites, giving the study area an unusually high potential for future hominid discoveries.

On the basis of a multidisciplinary approach we have unraveled the palaeo-earthquake history of a trenched section across the Peel Boundary Fault. The area shows at present one of the largest contrasts in relative motion on both sides of the fault on the basis of repeated levelling. The geological record for the last 25 thousand years, recovered in the trench, shows evidence of two heavy earthquakes (moment magnitude between 6.0 and 6.6), that occurred in a relatively short timespan around 15 thousands years ago. A third less severe event occurred somewhere in the mid Holocene. The time interval between the two large events is in the order of 1500 years, an interval comparable to that between the last volcanic explosions in the nearby Eifel area. Both records together seem to suggest a relation between large-scale faulting and volcanic activity in the nearby Eifel area, but this interpretation is based on one trench only and should be tested by opening more trenches in the zone that is assumed to be affected by these large events.
