Tonga underwater volcano eruption triggers tsunami advisories

Tongan geologists watched a massive plume of ash rise in the sky during a continuous eruption of the Hunga Tonga-Hunga Ha’apai volcano on Jan. 14. The Tonga Geological Services released images of what they said was a 5 km wide column of ash, gas, and steam rising 18-20 km above sea level. On Saturday, Jan. 15, a further volcanic eruption triggered tsunami alerts for several Pacific nations, Australia, New Zealand and on the Pacific coastlines of Japan and the U.S. For more info, please go to https://globalnews.ca/news/8513659/to...
