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.

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.
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.
Future events could damage the critical portion of the undersea network which links to Australia.
Volcanoes might seem like nature’s incinerators, but using them to burn up trash would be dangerous and disrespectful to indigenous people who view them as sacred.
To answer this question, it’s important to understand how PVMBG of the Ministry of Energy and Mineral Resources classify the physical events of Semeru and the corresponding alert level.
The eruption in East Java that claimed 22 lives on Saturday was likely triggered by weather conditions rather than by internal unrest inside Mount Semeru, which would have been easier to monitor.
Volcanic Moon rocks collected by a Chinese probe last year are around 2 billion years old, a new analysis shows. That’s a billion years younger than those brought back by the Apollo and Luna missions.
A key goal of the Chang'e-5 mission was to find evidence of some of the youngest volcanic eruptions on the Moon.
A previously unknown filtering process inside some volcanoes can cause magma to shoot out like champagne from a bottle - and perhaps even make it easier to forecast when a volcano is about to erupt.
The Rev. Sereno Edwards Bishop mobilized ship captains to track the extraordinary sunsets appearing around the world after Krakatau erupted in 1883.
How do organisms survive extreme conditions – and how can their adaptations help us develop better technology?
People tell tales to explain what they see – centuries later, scientists try to map handed-down myths onto real geological events.
Sonar scans of the Indian Ocean floor south of Christmas Island have revealed a Tolkeinesque landscape of towering peaks, ashen uplands and ominous volcanic craters.
Toba eruption caused temperatures to plummet by up to 10°C in some regions – but not where most humans lived.
When borders reopen, take an Aussie road trip and explore the continent’s unique geology, from meteorites in the Nullarbor Plain to rock formations that are billions of years old.
