What an Underwater Volcanic Eruption Looks Like

The Hunga-Tonga-Hunga-Ha'apai volcano near Tonga has been erupting occasionally for the past month. After a break in the action since January 5, it erupted again Thursday and Friday, but the biggest eruption was on Saturday (January 15), with an explosion that was heard 800 kilometers away in Fiji. A resulting tsunami hit Tonga's largest island Tongatapu, and tsunami advisories went out for parts of Japan, New Zealand's north island, and the US west coast this morning. Here's a video of the tsunami rolling in to Tonga.  

Tonga's next challenge is falling ash and acid rain. Let's see that eruption from another satellite image.
