GEM-SARA Topic 6 Workshop
14-15 May 2014
On Wednesday 14th and Thursday 15th of May 2014, a Scientific Workshop in the area of
seismic hazard assessment, will be held at the Observatório Nacional in Rio de Janeiro. The
workshop is part of the Global Earthquake Model (GEM) project, leaded by the GEM
Foundation in Italia. The project includes a South American component: GEM-SARA
(http://www.globalquakemodel.org/what/regions/south-america/).
One crucial step in the seismic hazard assessment is the estimation of ground-motion
generated by earthquakes at a given location away from the earthquake source. The “state-ofthe-art” practice uses empirical models built from regression analysis using recorded data.
The goal of the meeting is to identify all available records of significant earthquakes in South
America and gather the associated “metadata” regarding the event and the recording station.
The best processing scheme will also be defined in order to create a homogeneous database,
which will be used in the next steps of the project to compare with existing empirical GroundMotion Prediction models, and select and/or adjust those that best fit the recorded data in
South America.
The meeting will involve one official from the GEM Foundation, and a renowned specialist in
strong-motion record processing:
