Probabilistic tsunami hazard mapping is performed at Seaside, Oregon, the site of a pilot study that is part of the Federal Emergency Management Agency's (FEMA) effort to modernize its Flood Insurance Rate Maps (FIRMs). Because of the application of the study to FIRMs, we focus on developing aggregate hazard values (e.g., inundation area, flow depth) for the 1% and 0.2% annual probability events, otherwise known as the 100-year and 500-year floods. Both far-field and local tsunami sources are considered, each with assigned probability parameters.
