Watch! Tonga’s Underwater Volcano Eruption Seen From Space


New York: Satellite imagery captured the moment an underwater volcano erupted off the coast of Tonga on Saturday, Jan. 15, triggering a tsunami warning for several South Pacific island nations. The eruption caused a 1.2-metre tsunami, Australia’s Bureau of Meteorology said.

Each frame in this video is less than 10 minutes long, so the plume expanded quickly. Some experts estimated the shockwave expanded at an amazing 800 – 950 kph (500-600 mph.)

NASA’s GOES-17 satellite also captured this view:
