(2025) "Model simulation data of tsunami propagation in the Pacific Ocean" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/601921.

The simulation scenarios include two historical events, the September 16, 2025 tsunami generated by the Mw 8.3 Illapel, Chile earthquake and the March 11, 2011 tsunami generated by the Mw 9.1 Honshu, Japan earthquake. Also included are six scenarios generated by hypothetical Mw 8.6 earthquakes in the Alaska, Central America, South America, Kermadec, Kuil, and New Zealand-Tonga subduction zones, respectively.
