 This research aimed to develop a set of ground motion parameters for the Campos Basin region of Brazil using existing data and synthetically generated accelerations. The researchers first analyzed the seismic hazard of the region by looking at historical data and then used these results to generate a synthetic acceleration time history. They also looked at two recent earthquakes in the region to further refine their model. The resulting ground motion parameters can be used to inform the design of structures in the region.
