00:00Alaska witnessed a tsunami that climbed 1,180 feet up a mountainside.
00:05It happened in Tracy Arm on August 10, 2025, when a huge landslide crashed into a narrow fjord.
00:12More than 64 million cubic meters of rock plunged into the water,
00:17generating the second-highest tsunami run-up ever recorded.
00:20The surge stripped vegetation from nearby mountainsides, leaving enormous scars.
00:25But scientists found clues before the collapse.
00:28A nearby glacier had rapidly retreated.
00:31Heavy rain was falling, and thousands of tiny seismic tremors shook the area.
00:35Researchers say these signals could help shape warning systems for vulnerable coastal regions.
00:40By combining earthquake data, rainfall measurements, and glacier monitoring,
00:45scientists may identify rising danger.
00:48Such alerts cannot prevent every disaster,
00:50but they could give people farther down a fjord precious time to respond.
