The Hunga Tonga-Hunga Ha'apai volcano set new benchmarks for volcanic phenomena and efforts are under way to identify other submarine volcanoes around the world that could pose similar threats.

In 1983, a Canadian group helped rebuild traditional cooking houses in Tonga in the aftermath of a devastating cyclone. The Tonga Kitchens project offers lessons for Canadian aid today.
As Fiji did after 2016’s catastrophic cyclone, Tonga will likely face challenges with building materials and costs, and low levels of technical expertise. But these can be overcome.
We can’t prevent natural disasters from happening, but we can be better prepared for when they do.
Climate change doesn’t just affect the atmosphere and the oceans, it affects the Earth’s crust as well.
A phenomenon first theorized over 200 years ago is also a telltale sign of nuclear tests.
Tsunamis can be generated by underwater volcanic explosions thousands of miles away. The Jan. 15 explosion in Tonga resulted in tsunami advisories for British Columbia and all along the U.S. west coast.
Monitoring volcanoes is a bit trickier when they’re deep under the ocean’s surface.
Given their vital role in communications, the global economy and security, the rules governing undersea cables need overhauling.
Tsunamis aren’t just bigger-than-average waves. Triggered by undersea earthquakes or volcanic eruptions like the one in Tonga, they are fast, massive and potentially destructive. Here’s why.
Volcanic eruptions can wreak havoc in the upper atmosphere.
Australians tend to be fairly relaxed about the tsunami risk. But warnings from authorities to stay away from foreshore areas should not be ignored.
Future events could damage the critical portion of the undersea network which links to Australia.
The eruption is akin to a weapons-grade chemical explosion, and there could be several weeks or even years of major volcanic unrest to follow.
Tattooing tools made and used 2,700 years ago include two blades made on human bone.
