Report on the 2014 AIQUA Summer School "La geologia del quaternario applicata allo studio delle faglie attive: Dai terremoti alla microzonazione sismica"

We here summarise the activities carried out during the 2014 AIQUA Summer School, held from the 29th of September to the 3rd of October at Istituto Nazionale di Geofisica e Vulcanologia (INGV) of L'Aquila, and supported by INGV-Progetto Abruzzo. The school aimed at highlighting the major contribution of Quaternary geological investigation to the analysis of active and capable faults: this approach involves seismotectonic analysis and surface faulting hazard assessment on faults and deep seated gravitational slope deformations. The participants attended two days of classes, related to those topics, held by experts, and actively and largely joined the discussions raised during the lessons; furthermore, they took part to a three-day fieldtrip in the 2009 L'Aquila earthquake area and surroundings. Concepts and methods learned during the lessons were applied to selected case studies: these included the 2009 L'Aquila earthquake causative fault and other major active normal faults affecting the Gran Sasso Range and the middle Aterno river valley. Moreover, participants actively took part in still ongoing paleoseismological investigations that aimed at the reconstruction of the recent kinematic behaviour and slip history of the Assergi fault, a major active normal fault of the central Apennines.
