Résumé

This study present sedimentological and micromorphological evidence on the occurrence of an ancient seismic event of Roman age (2nd Century AD) in the ancient palustrine environments of the Guadalentín Depression (Murcia). Sedimentological (outcrop-scale ), textural and micromorphological (thin-section) analyses evidence clear signals of liquefactions, such as the development of convolute lamination, injection dikes and boudinage levels on sandy -silt materials at both meso and micro-scale. The study shows the capability of this kind of analyses in the iden tification of paleoseismic events with size ≤ 5.0 Mw on the sensitivity threshold (VI-VII) of the ESI07 Intensity Scale.
