![]() framework and comparing them with the macroseismic damage surveys made in 305 localities. The strong motion records of the Italian accelerometric network were analyzed and plotted in a shakemap making use of a G.I.S. This work has two main purposes: firstly it provides some new elaborations and comparisons regarding the seismic input and the damages in the area affected by the earthquake. ![]() Many small towns and villages, which have survived to the first earthquake, were heavily damaged during the October 30 earthquake. ![]() Nevertheless, while the earthquake of August 24 had a very destructive impact on a restricted area included in the above listed municipalities, the impact of the following seismic events was distributed on a larger portion of territory extending northwards in the Marche Region. 1), where many buildings had been strengthened after the 1997 earthquake. It has also to be considered that the October epicenters are located close to Norcia municipality (Fig. The events of October 26 and 30 didn’t cause any victim thanks to the fact that people had been already evacuated from damaged and vulnerable houses after the previous seismic events. The earthquake of October 30, which happened at 7:40 am, had a M W 6.5, being the largest event in terms of released energy occurred in Italy since the Mw 6.9 1980 Irpinia earthquake. On October 26, there were two strong aftershocks, the first at 19:10 with Mw 5.6 and the second at 21:18 with Mw 6.1. In these municipalities heavy damage and collapse of residential buildings were reported. Most of the victims were in the areas of Amatrice, Accumoli, and Arquata del Tronto. These events caused a total of 299 fatalities, 386 injured and about 4800 homeless (Italian Department of Civil Protection 2017). The mainshock occurred on August 24 at 3:36 am (local time) with epicenter close to Accumoli (Rieti province) and a magnitude Mw = 6.2 it was followed, at 4.33 am, by an aftershock with epicenter close to Norcia (Perugia province) and a magnitude Mw = 5.5. The seismic events which hit Central Italy on August 24, October 26 and Octohave caused casualties and major damage mostly to buildings and architectural heritage of the Italian regions of Abruzzo, Lazio, Marche and Umbria. The elevated level of destruction was mainly caused by the high vulnerability of the masonry buildings, mostly due to specific vulnerability factors such as the poor quality of masonry, the lack of connections between walls and the poor connection between external walls and floors. The damage level resulted very high with more than 60% of the inspected buildings showing partial or total collapse. On the basis of an inspection survey made in September 2016, a map of the damage patterns of the buildings in the historical center was elaborated according to the EMS 98 classification. The 260 strong motion records obtained for the first event were analyzed and plotted in a shakemap, comparing them with the macroseismic damage surveys made in 305 localities. There were 298 victims, 386 injured, about 5000 homeless, and the historical center of the town suffered a great number of partial and total collapses. The impact of the two seismic events of August 24th 2016 on the municipality of Amatrice was highly destructive.
