The most significant geological effects resulting from the strong seismic events that struck a vast area of Central Italy on October 26 and 30, 2016, are illustrated through a gallery of around one hundred photographs. The new publication in the Miscellanea editorial series of theistituto Nazionale di Geofisica e Vulcanologia (INGV) A new photographic dataset of the coseismic geological effects originated by the Mw5.9 Visso and Mw6.5 Norcia earthquakes (26th and 30th October 2016, Central Italy).
Author of the work, the Emergeo Group (http://emergeo.ingv.it/), an INGV seismic emergency operational team, made up of geologists and technicians specialized in carrying out initial investigations and surveys on the geological effects of a seismic event.
The Visso earthquake of 26 October (M5.9) and, above all, that of Norcia of 30 October (M6.5) originated new and more extensive cracks on the surface, compared to those produced two months earlier by the Amatrice earthquake.
The Emergeo Group has collected about 7000 observations of various surface cosismic effects (ruptures, fractures, landslides, liquefaction, etc.) in an area of about 500 km2; during the post-event survey, around 15000 photographs were taken, summarized in the Miscellaneous published and downloadable from the Series website http://www.ingv.it/editoria/miscellanea/2017/miscellanea38/
This latest issue of the INGV Miscellanea is closely linked to a previous issue (n.34 of 2017), dedicated to the geological effects produced by the Amatrice earthquake of 24 August 2016.
