NASA's Guardian Tsunami Detection Tech Catches Wave in Real Time

While GNSS processing methods on Earth correct for such distortions, GUARDIAN uses them as clues. The software scours a trove of data transmitted to more than 350 continuously operating GNSS ground stations around the world. It can potentially identify evidence of a tsunami up to about 745 miles (1,200 kilometers) from a given station. In ideal situations, vulnerable coastal communities near a GNSS station could know when a tsunami was heading their way and authorities would have as much as 1 h

Satellite Captures Awesome Power of Tsunami Triggered by Epic Russian Quake

In late July, the sixth biggest earthquake in recorded history struck off the coast of Russia’s Kamchatka Peninsula. The magnitude 8.8 quake triggered a tsunami that sent waves across the Pacific, prompting widespread warnings and some evacuation orders. Data released Thursday, August 14, by NASA Earth Observatory captures this global event in striking detail. The Surface Water and Ocean Topography (SWOT) satellite, a joint venture between NASA and the French space agency CNES (Centre National

The Pacific Dodged a Monster Tsunami After One of the Biggest Quakes Ever. Here’s Why

The earthquake near the east coast of the Kamchatka Peninsula in Russia on July 30, 2025, generated tsunami waves that have reached Hawaii and coastal areas of the U.S. mainland. The earthquake’s magnitude of 8.8 is significant, potentially making it one of the largest quakes ever recorded. Countries around much of the Pacific, including in East Asia and North and South America, issued alerts and, in some cases, evacuation orders in anticipation of potentially devastating waves. Waves of up to

6th Biggest Earthquake Ever Recorded Strikes Pacific, Triggers Widespread Tsunamis: What We Know So Far

One of the strongest earthquakes in recorded history struck off the coast of Russia on Tuesday, July 29, triggering a tsunami that sent waves into Japan, Hawaii, and the U.S. west coast. The magnitude 8.8 earthquake hit offshore of the Kamchatka Peninsula in Russia’s far east on the evening of Tuesday, July 29, at a depth of about 13 miles (21 kilometers), according to the U.S. Geological Survey (USGS). The epicenter was located roughly 74 miles (120 kilometers) west-northwest of the city of Pe
