The 2025 tsunami is shattering old models, thanks to observations from space. On July 29, 2025, the world’s sixth biggest recorded earthquake struck Russia, triggering a tsunami whose waves reached as far as the U.S.’s West Coast. Data from an unexpected source —space—has shed unexpected light on this oceanic reaction.

More than 25 million cubic yards of rock and ice broke loose and plunged into Greenland's Dickson Fjord, creating a 650-foot-high mega-tsunami

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,

More than six centuries later, scientists say that the skeletons hold vital clues about the history of tsunamis.

Guam’s tsunami preparedness was put to the test on July 30 in the wake of a magnitude 8.8 earthquake that hit Russia.
