摘要：

High-resolution textural signatures of an earthquake-induced historical 'homogenite' layer are presented, as well as its 3D distribution. This homogeneous deposit is correlated with the AD 1822 event (VII-VIII MSK intensity), the main historical earthquake of the French outer Alps, using Pb-210 dating and historical chronicles. During this earthquake a violent lake water oscillation was reported (seiche effect). In the present study we discuss the influence of lake water oscillations during earthquake-induced subaqueous slide, through a pluridisciplinary analysis of subbottom sediments including high-resolution seismic, sidescan sonar and short gravity coring.
