GNGTS 2016 - Atti del 35° Convegno Nazionale

72 GNGTS 2016 S essione A matrice avalanches, liquefactions etc.). Field mapping was mainly performed by using smartphones equipped with software that use the phone’s GPS, compass and orientation sensors. The Rocklogger application (rockgecko.com ) was used to measure the characteristics of the observed coseismic effects (type of observation, strike, throw, heave, etc.). GPS track loggers were used for monitoring the survey coverage and planning future campaigns. The post-earthquake survey of surface ruptures has been supported by a helicopter flight and by low-altitude aerial platforms Fig. 1 – Location of the observations collected in the field. Normal faults are compiled from geological maps (Centamore et al. , 1992; Pierantoni et al. , 2013). Hillshade from TINITALY 10m-DEM (Tarquini et al. , 2012). The 24 August 2016 mainshock and largest aftershock are reported with red stars. TDMT focal mechanisms available at http://cnt.rm.ingv.it/event/7073641 and http://cnt.rm.ingv.it/event/7076161. DGSD (deep-seated gravitational slope deformations) with evidence of coseismic fracturing are shown.
