NEOWAVE Regional Tsunami Model: Maritime Hazards: American Samoa: Tutuila: Pago Pago

Niveau marin État de la mer Courants de surface

Non-hydrostatic Evolution of Ocean WAVEs (NEOWAVE) regional tsunami model for Pago Pago Harbor on the island of Tutuila in American Samoa, categorized by earthquake magnitude and subduction zone. Includes nearshore hazard maps of surge, drawdown, and current for hypothetical advisory and warning-level tsunamis from potential sources at the Kuril-Kamchatka, New Hebrides, Tonga, and Peru-Chile subduction zones. Data are gridded at approximately 9-m 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 surge, drawdown, and current described by these data.
