Summary

Story summary

On July 29, 2025, a magnitude 8.8 earthquake off Russia's Kamchatka Peninsula triggered a Pacific-wide tsunami.
NASA's SWOT satellite captured high-resolution images showing a braided tsunami pattern rather than a single wave.
Researchers found dispersive effects improve tsunami simulations, challenging models that treat large tsunamis as non-dispersive.
Trailing waves may influence a main wave's impact on coastlines, underscoring the need for updated forecasting models that use diverse data sources.
