🚀 The earthquake at a glance

The 1980 Irpinia earthquake (Italian: Terremoto dell'Irpinia) took place in Italy on 23 November 1980, with a moment magnitude of 6.9 and a maximum Mercalli intensity of X (Extreme). It left at least 2,483 people dead, at least 7,700 injured, and 250,000 homeless. Wikipedia

Ground shaking

The estimation of the ground shaking has The folder OpenQuake_gmfs stores the required input files to generate the ground motion fields considering different rupture solutions and conditioning the ground shaking to the recording stations for the event, when available. The figures below present an example of the results, showing the median ground motion fields with and without conditioning the ground shaking for the rupture and ground motion model that indicates the lowest nominal bias.

☄️ Consequences

The information collected for the consequences of the event and the corresponding references is available in the Impact folder. When available, information at different geographical levels is provided considering the building damage, economic losses and human impact.

A summary of the main consequences of the event is available in the earthquake_information.csv file:
