Abstract
Luminescence ages help provide a time scale for recurrent surface ruptures on a normal fault in the southern Arava, Israel. The dated samples come from alluvium and colluvium along a fault scarp north of Elat. The ages, obtained mainly by infrared stimulation of sand-size potassium feldspar grains, accord with geomorphic age estimates from soils and degraded scarps. Four large earthquakes occurred between 37,000 and 14,000 yr ago. Five smaller earthquakes occurred thereafter continuing until recent times. The mean recurrence interval for earthquakes of magnitudes greater than 6 is about 4000 yr.
