Abstract
Field work on palaeoseismicity was carried out within the Aquitain bas in (France). This structural study of cross-section led to the discove ry of tectonic surface ruptures in a middle Pleistocene alluvial terra ce of the River Adour. The origin of this deformation is probably seis mic. The presence of these surface ruptures shows the likely evidence of a great palaeoearthquake, in an area where the historical and instr umental seismicity is very weak or absent. These observations are fitt ed into the regional tectonic framework.
