A magnitude 6.0 earthquake struck Hawaii's Big Island, causing widespread shaking but no eruption or tsunami. Authorities confirmed the quake was due to tectonic activity, not volcanic processes.

The NASA-USGS Landsat satellite images show the dramatic changes to the landscape. In one photo taken on July 26, 2025, the fjord is surrounded by green vegetation. In the second image, taken nine days after the landslide on August 19, the fjord is dominated by a gray scar made by the cascading rock.

The world’s second-tallest tsunami wave on record tore through the remote Tracy Arm fjord in Alaska last August, leaving immense destruction in its wake.

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

If you’re one of the roughly 1.6 million people who took a cruise in Alaska last year, chances are you sailed through the Tracy Arm fjord. The picturesque, narrow fjord is a popular sightseeing area and is part of the Tongass National Forest, about 40 to 50 miles south of the capital city of Juneau.

A tsunami in Alaska's Tracy Arm Fjord in 2025, triggered by a landslide, became the second largest ever recorded. The initial wave was 100 meters high and stripped vegetation up to 1,578 feet high.

Tracy Arm, a narrow inlet with steep walls, sits at the edge of two glaciers. Both are fed by the nearby Stikine ice field, which has been rapidly thinning for decades, causing the glaciers to shrink and retreat. Higher global temperatures, driven by greenhouse gases, are a major factor in the melting.

A three-meter (9.8-foot) tsunami warning was issued for Japan on Monday after a strong 7.4 magnitude earthquake struck off the northeastern coast, according to the Japan Meteorological Agency and the US Geological Survey.

Petra Nemcova may be known as a supermodel and survivor, but she's looking better than ever in 2026. The Czech beauty, 46, rose to stardom as a supermodel who hit the runways and pages of magazines like Harper's Bazaar and Elle.

Scientists are renewing warnings about mega-tsunami risk to three US coastlines — the Pacific Northwest, Alaska, and Hawaii. New geological modelling shows the Cascadia Subduction Zone is overdue for a magnitude 9.
