2009 Cinchona earthquakeoccurred at 1:21:35 pm local time on January 8 with an Mwc magnitude of 6.1 and a maximum Mercalli intensity of VII (Very strong). The shock took place in northern Costa Rica, 30 kilometres (19 mi) north-northwest of San José and was felt throughout Costa Rica and in southern central Nicaragua. (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:
