The eruption in the South Pacific is so powerful that it can be seen from space

A tsunami triggered by a massive underwater volcanic eruption hit the Pacific island nation of Tonga and prompted warnings from other countries. The volcano is so loud that it can be heard 800 kilometers away.

The underwater eruption of the Hunga Tonga-Hunga Ha’apai volcano occurred 65 kilometers south of Tongatapu, the main island of Tonga. It’s so massive that it’s clearly visible on images from several satellites orbiting Earth, including the National Oceanic and Atmospheric Administration (NOAA) GOES-West. It has prompted several other countries, including the United States, to issue tsunami warnings.

Video on social media showed a huge plume of grey smoke rising from the sea and into the sky. According to the Tonga Geological Service, the smoke, gas and ash reached a height of 20km. The ash cloud was also reported to be nearly 700 kilometers wide.

Ash fell on Tonga’s capital Nuku’alofa, according to some witnesses – the eruption was reported to be heard across the South Pacific.

The National Tsunami Warning Center in Palmer, Alaska, said a tsunami warning was also issued for the west coast of the United States, including California, Oregon, Washington and Alaska.

New Zealand’s National Emergency Management Agency said people on the north and east coasts of the North Island could see “Unpredictable surges on the coast.” Authorities in New South Wales, Australia tell people “Get out of the water, away from the direct water’s edge.”

Videos posted on social media showed huge waves flooding the coast of Tonga and destroying fences, smashing through some town streets and submerging local churches.
