Gold was the first attraction, but late in the 1500s the Portuguese became obsessed with the idea that there were silver mines in Africa.
A change in the voting age wouldn’t have major advantages in South Africa.
Donald Trump’s deportation orders are raising concerns across the Pacific about a possible influx of returned migrants – and a lack of funds to help them integrate into society.
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.
Winnie Dunn has made it her project to bring a more sensitive intercultural understanding to an unfamiliar readership
The author of a major new essay collection reflects on the shifting cultural and political realities in the Pacific, and why it remains an ‘unequal ocean’.
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.
