Pressure changes in the summit reservoirs of Kīlauea may help explain the number of earthquakes — or seismicity — in the volcano’s upper East Rift Zone.

Careful analysis of volcano’s plumbing system may give tips on pending...

U of T's Jeremy Rimando sets up Differential Global Positioning System (DGPS) survey equipment to measure the amount of displacement on the Las Chacras Fault in San Juan, Argentina.

Research could protect cities in active earthquake zones

Researchers on the MV Steller are in front of the terminus of Alaska's LeConte Glacier in August 2016. An over-the-side pole holds the sonar instrument that collects data on the subsurface ice face as the vessel moves slowly through the icy water. Credit: David Sutherland

Strange new species of duck-billed dinosaur identified

An artist’s rendering of Auroraceratops shows its bipedal posture as well as the beak and frill that characterize it as a member of the horned dinosaurs. Paleontologists from Penn led a team in characterizing this species, discovered in China

Tamu Massif made news in 2013, thought to be the world's largest volcano. New research offers a better look at the volcano's formation and throws doubt on that claim.

Istanbul: Seafloor study proves earthquake risk for the first time

When carbon emissions pass a critical threshold, it can trigger a spike-like reflex in the carbon cycle, in the form of severe ocean acidification that lasts for 10,000 years, according to a new MIT study.

Breaching a ‘carbon threshold’ could lead to mass extinction

Polar ice caps on Mars are a combination of water ice and frozen CO2. Like its gaseous form, frozen CO2 allows sunlight to penetrate while trapping heat. In the summer, this solid-state greenhouse effect creates pockets of warming under the ice, seen here as black dots in the ice.

A material way to make Mars habitable
