A NASA satellite caught a giant tsunami doing something scientists didn’t expect
Our take
A recent earthquake near Kamchatka provided a unique opportunity for scientists to analyze tsunami behavior through data captured by NASA’s SWOT satellite. This satellite delivered an unprecedented, high-resolution view of the tsunami as it traversed the Pacific Ocean, revealing a complexity and scattering of waves that challenged prior assumptions. The findings indicate that large tsunamis do not move as singular, stable entities. Additionally, ocean sensors confirmed that the earthquake's rupture extended longer than previously modeled, suggesting significant implications for future tsunami modeling and prediction efforts.
When a huge earthquake struck near Kamchatka, the SWOT satellite captured an unprecedented, high-resolution view of the resulting tsunami as it crossed the Pacific. The data revealed the waves were far more complex and scattered than scientists expected, overturning the idea that large tsunamis travel as a single, stable wave. Ocean sensors confirmed the quake’s rupture was longer than earlier models suggested. Together, the findings could reshape how tsunamis are modeled and predicted.
