From: Seismic signature of the deadly snow avalanche of January 18, 2017, at Rigopiano (Italy)

(a) Seismic stations of the INGV-network (triangles) installed in the Abruzzo area. The yellow stars indicate the earthquakes on January 18, 2017, which occurred at UTC 09:25:40 (Mw5.1), 10:14:09 (Mw 5.5), 10:25:23 (Mw 5.4), and 13:33:36 (Mw 5.0). Only station GIGS, situated at 17 km W of Rigopiano, recorded a signal related to the avalanche that hit the hotel. (b) The avalanche caused a dislocation of the hotel’s upper floor by 48 m in ~ 70°N direction (measured by the dislocation from the SW-edge of the building from “pre” to “post”) and a ~ 13° anticlockwise rotation.
