Underwater sound signals created by 2022’s enormous Hunga eruption have pointed scientists to a new way to warn people of unpredictable volcanic tsunamis.

Our new research predicts how Hunga Tonga’s vast underwater eruption in 2022 will change winters worldwide for years to come – as far away as Australia, North America and even Scandinavia.
The eruption was so large, it created its own space weather and satellite technology disruptions – here’s how.
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.
A phenomenon first theorized over 200 years ago is also a telltale sign of nuclear tests.
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.
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.
