The incredible eruption was captured on satellite imagery and could be seen from space. “Perhaps the most violent, explosive volcanic eruption ever observed on satellite,” meteorologist and atmospheric scientist Matthew Cappucci tweeted. “Plumes to 100,000 feet, an outward explosion of gravity waves, an enormous mass of pyrocumulonimbus/volcanic thunderstorms, tens of thousands of lightning strikes, a tsunami… wow.”
A tsunami slammed into the Pacific island nation of Tonga on Saturday after an underwater volcano eruption sent waves barreling as far away as Oregon.
U.S. National Weather Service forecaster William Churchill called it “one of the most incredible satellite animations I’ve ever seen… Waves upon waves. Simply incredible.”
The country’s largest island, Tongatapu, saw the strongest impact from the eruption 40 miles away. Video captured from the island showed waves streaming down streets, flooding its capital, Nuku’alofa, and prompting the evacuation of Tonga’s King Tupou VI, according to CNN.
Residents reported seeing waves crash through physical barriers as they pummeled the islands, halting everything from choir practice to dinner. Ash and smoke clouded Nuku’alofa, and communications were knocked out.
No casualties have been reported yet but communication with the island remains spotty.
“My first instinct was to take cover under the table,” Tongan Mere Taufa told the New Zealand news outlet Stuff. “I grabbed my little sister, and screamed at my parents and others in the house to do the same.”
“You could just hear screams everywhere, people screaming for safety, for everyone to get to higher grounds,” she added.
The National Weather Service issued tsunami advisories for virtually the entire U.S. west coast in light of the storm. Its Portland office said waves of 1 to 3 feet were reported along the Oregon and Washington coast, while its Los Angeles office urged its residents to be wary of rip currents. Australia, Fiji, Samoa and New Zealand also issued alerts. Story continues
“First wave may not be the highest so later waves my be larger,” the Portland NWS tweeted. This is the second eruption of the underwater volcano Hunga-Tonga-Hunga-Ha’apai in as many days. Saturday’s explosion dwarfed Friday’s blast, as captured by the National Weather Service in Honolulu. It previously erupted in 2014, forming a new island.
