A NASA satellite caught a giant tsunami doing something no one expected
Summary
A NASA satellite tracked a Pacific-wide tsunami from a magnitude 8.8 earthquake off Kamchatka, capturing unusually detailed measurements of the waves as they traveled. The satellite data showed unexpected wave behavior and indicated the quake rupture was larger than early models suggested.
Why it matters
Better early estimates of rupture size and tsunami propagation can tighten warning accuracy and reduce both missed risk and unnecessary evacuations.
