WELLINGTON, New Zealand (AP) — An undersea volcano erupted in spectacular fashion Saturday near the Pacific nation of Tonga, sending tsunami waves crashing across the shore and people rushing to higher ground. The eruption cut the internet to Tonga, leaving friends and family members around the world on Sunday...

The body of a missing British charity worker, who was swept away while trying to save her dogs in the Tonga tsunami, has been found, her family revealed Monday. Angela Glover, 50, became separated from her husband, James, on Saturday when a tsunami wave triggered by a volcanic eruption crashed into them outside their home in Tonga’s capital, Nuku’alofa.

A rare volcano-triggered tsunami sparked by the eruption of Hunga Tonga-Hunga Ha'apai in Tonga could have been caused by shock waves or shifting underwater land, experts said Monday. "A volcanic-source tsunami event is rare but not unprecedented," a post on the website for New Zealand's geological hazard monitoring system GNS...

The tsunami that rippled across the Pacific Ocean on Saturday may have been a good test run for the Pacific Northwest’s emergency alert systems, but it’s not yet clear how useful the experience will be in preparing Oregonians for a major disaster. Caused not by an earthquake but...

Australia and New Zealand sent surveillance flights on Monday to assess damage in Tonga, which is isolated from the rest of the world after the eruption of a volcano that triggered a tsunami and blanketed the Pacific island with ash. Australia’s Minister for the Pacific Zed Seselja said initial reports...

Although there wasn't any major damage caused by a tsunami surge that was triggered by an underwater volcano eruption in the South Pacific Saturday, some Southern California coastal areas definitely saw its effects.

The Tsunami advisory had largely been cancelled by 9 p.m. along the California coast, including in Los Angeles and Orange counties. However it remained in effect in San Luis Obispo and Santa Barbara counties.

SANTA CRUZ, Calif. - Santa Cruz was one of the hardest hit areas after the Tongan volcano eruption triggered a tsunami advisory for the California coast on Saturday. There was flooding in some areas along the coast as the dangerous waves reached the harbor. Randy Chase said he was visiting...

A new insight into magnetic fields, generated by tsunamis in seawater, might lead to earlier tsunami warnings for people who would otherwise be in danger. Scientists said December 21, 2021, that the magnetic fields generated by tsunamis arrive before the waves themselves. They said the magnitude of a tsunami’s magnetic field can help determine the potential height of the tsunami wave before it strikes land. Scientists can detect a tsunami’s magnetic fields only up to a few minutes earlier than previous methods. Yet those few minutes might provide precious time for people to seek higher ground.

The dramatic collapse of Indonesia’s Anak Krakatau volcano in December 2018 resulted from long-term destabilizing processes, and was not triggered by any distinct changes in the magmatic system that could have been detected by current monitoring techniques, new research has found. The volcano had been erupting for around six...
