Undersea Volcano Eruption Triggers Massive Shockwave, Tsunami Strikes South Pacific Island
An undersea volcanic eruption occurred 40 miles off the coast of the South Pacific country of Tonga on Saturday.
Satellite imagery shows the eruption unleashed a massive shockwave as a plume of ash was flung 12.4 miles into the atmosphere.
US Storm Watch said the eruption was the “most violent” eruption ever captured on satellite footage.
Some have compared the eruption to the “Hiroshima” nuclear bomb explosion.
Shortly after the eruption, a tsunami warning was posted for Tonga. An advisory was issued for New Zealand’s North Island. CNN affiliate Radio New Zealand (RNZ) said a tsunami hit Tonga’s capital, Nuku’alofa, flooding coastal roads and properties.
RNZ said Tonga’s King Tupou VI was evacuated from the Royal Palace, and residents were told to flee to higher ground.
One Tongan resident told Yahoo News the eruption was “catastrophic,” and ash and rock rained down on the capital.
Twitter user Dr. Faka’iloatonga Taumoefolau posted a video showing waves coming ashore.
“Can literally hear the volcano eruption, sounds pretty violent,” he wrote. In another post, he said: “Raining ash and tiny pebbles, darkness blanketing the sky.”
Prof Shane Cronin, a volcanologist at the University of Auckland, told BCC this eruption is the biggest Tonga has seen in three decades.
“This is a pretty big event – it’s one of the more significant eruptions of the last decade at least.
“The most remarkable thing about it is how rapidly and violently it’s spread. This one was larger, a much wider lateral spread, much more ash was produced. I expect there to be many centimetres of ash that have been deposited on Tonga,’ Cronin said.
