Magma influx explains short-lived bulge at Tanzania's Ol Doinyo Lengai volcano

Phys.org: Earth science - Sun, 09/20/2026 - 15:00

In 2024, D. Sarah Stamps' team detected and tracked a short-lived bulge in the land around a volcano in Tanzania. In a paper published Sep. 18, Stamps identified the cause of the uplift: 1 million cubic meters of magma pouring into an existing magma reservoir about 1.8 miles (2.9 kilometers) underground.

Reconstructing the Great Miami Hurricane of 1926

Phys.org: Earth science - Sat, 09/19/2026 - 19:30

The first storm warning for the Miami area wasn't issued until only a few hours before the powerful cyclone made landfall just south of downtown, leaving residents with little time to prepare for what would become the hurricane of their nightmares.

Australia's vast Nullarbor Plain hides deep caves that can teach us about alien worlds

Phys.org: Earth science - Sat, 09/19/2026 - 18:00

Stretching more than 200,000 square kilometers (77,000 square miles) across southern Australia, the vast, flat plains of the Nullarbor mark one of the world's largest regions of limestone. It formed when an ancient shallow sea retreated some 14 million years ago.

Bringing ice sheets to life: Releasing a dynamic ice sheet modeling workflow for Australia's climate model

Phys.org: Earth science - Sat, 09/19/2026 - 17:00

Ice sheets are fundamental components of the Earth system. Antarctica and Greenland, the two ice sheets currently on Earth, don't just affect their own regions: What happens on these vast masses of land ice influences weather, climate, society and the environment around the planet.

How narwhal 'scientists' track Arctic warming

Phys.org: Earth science - Sat, 09/19/2026 - 15:30

The fight against climate change has a new, spiral-tusked ally: the narwhal.

Sea surface temperature biases shift the North Pacific jet stream southward, study finds

Phys.org: Earth science - Sat, 09/19/2026 - 09:50

Climate models are numerical models used to project future climate change. They simulate the climate from the present into the future by calculating changes in the atmosphere, ocean and other components of the climate system. However, simulations of the present-day climate do not perfectly reproduce observations and contain various biases. The model characteristics that cause these biases can also affect simulations of the future climate. Understanding the causes and impacts of present-day climate biases is therefore important for improving the reliability of future climate projections.

North Korea's nuclear testing may have triggered hundreds of earthquakes over several years

Phys.org: Earth science - Fri, 09/18/2026 - 21:00

Between 2006 and 2017, North Korea conducted six underground nuclear tests at its vast testing site at Mount Mantap in North Hamgyong province. Typically, underground explosions trigger an intense burst of minor earthquakes that die down once testing stops. But geologists have detected far more seismic activity after the final detonation, and it has persisted for years.
