Simulation Shows How Tonga Tsunami Spread Across the Pacific

The National Oceanic and Atmospheric Administration has released a simulation of last month’s tsunami that triggered warnings in Humboldt County and around the Pacific. The “tsunami propagation” animation, put together by the Tsunami Research NOAA Pacific Marine Environmental Laboratory, shows tsunami waves and ocean disruption produced by the massive volcanic eruption on the uninhabited South Pacific island of Hunga Tonga-Hunga Ha‘apai on January 15.
