Computational tool helps forecast volcano slope collapses and tsunamis

Phys.org: Earth science - Fri, 10/03/2025 - 16:37

For people living near volcanoes, danger goes well beyond lava flows and clouds of ash. Some explosive eruptions can lead to dramatic collapses of the sides of a volcano, like those at Mount St. Helens, Washington, and Anak Krakatau, Indonesia. The latter triggered tsunamis blamed for most deaths from its historic eruptions in 1883.

Millions of buildings at risk from sea level rise, analysis finds

Phys.org: Earth science - Fri, 10/03/2025 - 15:34

Sea level rise could put more than 100 million buildings across the Global South at risk of regular flooding if fossil fuel emissions are not curbed quickly, according to a new McGill-led study published in npj Urban Sustainability.

Natural barriers in northern Sweden's rivers challenge downstream assumptions

Phys.org: Earth science - Fri, 10/03/2025 - 14:52

Rivers in northern Sweden do not always become wider or richer in species further downstream. Natural barriers shape the flow and stop plants from spreading, new research from Umeå University shows. The study is published in the journal Communications Earth & Environment.

Antarctica sees similar climate change effects as Greenland: Study

Phys.org: Earth science - Fri, 10/03/2025 - 14:40

The planet's warming climate is having effects in Antarctica that increasingly resemble those observed in the Arctic, meaning global sea levels could rise faster than previously predicted, Danish researchers warned on Friday.
