Abstract
The Tertiary Cevennes fault presents typical geomorphic characters of active faults. Its trace is sharp on SPOT images and air photographs. It is segmented (15-30 km) and has locally multiple strands. Along the main fault trace, abandoned valleys and terrace risers of the Herault and Gardon rivers are offset sinistrally by several hundreds of metre s. This suggests that the fault is an active Quaternary fault whose le ft slip-rate may range between 0.1 and 2 mm yr(-1). (C) Academie des s ciences/Elsevier, Paris.
