NEOWAVE Regional Tsunami Model: Guam: Merizo

Non-hydrostatic Evolution of Ocean WAVEs (NEOWAVE) regional tsunami model for Merizo village and Cocos Island along the south shore of the island of Guam. Provides nearshore hazard maps of inundation depth based on preferred maximum and maximum considered earthquakes at both local and distant sources. Because tsunami waves from a local Mariana earthquake can reach Guam's shores in less than 10 minutes, the resulting inundation is considered separately from distant tsunamis, which can take at least 2 hours to reach Guam. Data are gridded at approximately 9-m (30-ft) resolution referenced to the WGS84 coordinate system and use a vertical datum of mean sea level (MSL). This shock-capturing, dispersive wave model computes tsunami generation, propagation, and inundation for complex flow patterns in shelf and reef environments. It has been validated with analytical, laboratory, and field benchmarks and is approved by the National Tsunami Hazard Mitigation Program. These hazard maps cover tsunamis only; other potential hazards such as wind waves and swells would be additive to the inundation described by these data.
