Volcano erupts in Pacific, West Coast under tsunami advisory

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 still anxiously trying to get in touch to figure out if there were any injuries and the extent of the damage. Even government websites and other official sources remained without any updates.

Satellite images showed a huge eruption, with a plume of ash, steam and gas rising like a mushroom above the blue Pacific waters. A sonic boom could be heard as far away as Alaska.

Tsunami advisories were issued for Hawaii, Alaska and the U.S. Pacific coast. The U.S. Geological Survey estimated the eruption caused the equivalent of magnitude 5.8 earthquake. Scientists said tsunamis generated by volcanoes rather than earthquakes are relatively rare.

The Tonga Meteorological Services said a tsunami warning was declared for all of the archipelago, and data from the Pacific tsunami center said waves of 80 centimeters (2.7 feet) were detected.

Rachel Afeaki-Taumoepeau, who chairs the New Zealand Tonga Business Council, said she hoped the relatively low level of the tsunami waves would have allowed most people to get to safety, although she worried about those living on islands closest to the volcano. She said she hadn’t yet been able to contact her friends and family in Tonga.

“We are praying that the damage is just to infrastructure and people were able to get to higher land,” she said.

Tonga gets its internet via an undersea cable from Suva, Fiji, which presumably was damaged. All internet connectivity with Tonga was lost at about 6:40 p.m. local time, said Doug Madory, director of internet analysis for the network intelligence firm Kentik.

Southern Cross Cable Network, the company that manages the connection, does not know yet “if the cable is cut or just suffering power loss,” chief technical officer Dean Veverka said.

The Fiji-based Islands Business news site reported that a convoy of police and military troops evacuated Tonga’s King Tupou VI from his palace near the shore. He was among the many residents who headed for higher ground.

On Tonga, home to about 105,000 people, video posted to social media showed large waves washing ashore in coastal areas, swirling around homes, a church and other buildings.

New Zealand’s military said it was monitoring the situation and remained on standby, ready to assist if asked.

In Hawaii, the Pacific Tsunami Warning Center reported waves that measured half a meter (1.6 feet) in Nawiliwili, Kauai and 80 centimeters (2.7 feet) in Hanalei. The National Weather Service said there were reports of boats getting pushed up in docks, but the hazard diminished as the morning went on.

“We are relieved that there is no reported damage and only minor flooding throughout the islands,” the tsunami center said, describing the situation in Hawaii. The tsunami advisory for the islands was lifted about 11 hours after the eruption more than 4,828 kilometers (3,000 miles) away.
