NEOWAVE Regional Tsunami Model: Maritime Hazards: Guam: Agana and Tumon Bays

Offshore data are gridded at approximately 90-m resolution while in-harbor data are approximately 9-m resolution. Includes offshore surge and current based on maximum considered tsunamis as well as in-harbor hazard maps of surge, drawdown, and current for hypothetical advisory and warning-level tsunamis from potential sources at the Mariana, Nankai, Philippine, and New Guinea subduction zones.

Data are referenced to the WGS84 coordinate system, and the vertical datum is 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.
