At approximately 6:24 AM CET on the morning of 22 March 2020, an earthquake of magnitude 5.3 Mw, 5.5 ML, hit Zagreb, Croatia, with an epicenter 7 kilometres (4.3 mi) north of the city centre. The maximum felt intensity was VII–VIII (Very strong to Damaging) on the Medvedev–Sponheuer–Karnik scale. The earthquake was followed by numerous aftershocks, the strongest of which with a magnitude of 5.0. It was the strongest earthquake in Zagreb since the 1880 earthquake and caused substantial damage in the historical city center. More than 1,900 buildings were reported to have been damaged to the point of becoming uninhabitable. The earthquake was also felt in Slovenia. One person was killed and 27 others were injured. The earthquake occurred during the coronavirus pandemic and complicated the enforcement of social distancing measures set out by the Government of Croatia. It occurred during the Croatian Presidency of the Council of the European Union. The direct earthquake damage inflicted on Zagreb and Krapina-Zagorje County was estimated at 86 billion Croatian kuna (€11.5 billion). Wikipedia
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.
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:
