EnglishBetween August and October 2016, the Central Italy area, along the Apennine chain, has undergone a seismic sequence with three major earthquake events. The first event, with moment magnitude M6.1, occurred on 24 August 2016, the second (M5.9) on 26 October, and the third (M6.5) on 30 October 2016. Each event triggered a substantial number of coseismic landslides. The large majority of them are rock falls. For each mainshock, we analyze the spatial distribution of observed earthquake-induced landslides. Our analysis shows that data from this earthquake sequence are in good agreement with empirical relationships reported in the literature. We correlate the outermost landslide limits with peak ground acceleration (PGA) and peak ground velocity (PGV) spatial distributions, evaluated applying Kriging of within-event residuals. Values of PGA at the landslide limits for this seismic sequence are comparable to those observed during other earthquakes of comparable magnitude.
