Rapid estimation of the seismic impact through the active contribution of the civil protection volunteers

Immediately after an earthquake, a rapid estimation of the seismic impact is crucial to carrying out a prompt and appropriate Civil Protection response. This is particularly important in districts characterized by frequent and moderate-to-high seismicity, as is the case in the north-eastern part of Italy. In this paper, the authors illustrate an innovative approach developed in the Friuli Venezia Giulia Region (in north-eastern Italy), based on the active contribution of Civil Protection volunteers. The methodology is based on the rapid and pre-codified communication of the earthquake effects, focusing on two main aspects: (i) the observed effects on people and buildings in the urban areas, and (ii) the structural and non-structural damage observed on pre-identified buildings. In particular, this paper illustrates the methodology and its integration into the seismic emergency plans of the municipalities in the Friuli Venezia Giulia Region and discusses the first test, which occurred during a full-scale exercise and on the occasion of recent minor earthquakes affecting the area.
