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.

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.

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.

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.
