2012 Costa Rica earthquakeoccurred at 08:42 local time (14:42 UTC) on September 5. The epicenter of the 7.6 Mw earthquake was in theNicoyaPeninsula, 11 kilometers east-southeast of Nicoya. A tsunami warning was issued shortly afterwards, but later cancelled. Two people are known to have died, one from a heart attack and another, a construction worker, crushed by a collapsing wall. It was the second strongest earthquake recorded in Costa Rica's history, following the 1991 Limon earthquake. (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:
