Deep Drilling Reveals Puzzling History of Campi Flegrei Caldera
Results show that caldera collapse attributed to a super eruption almost 40,000 years ago was smaller than what scientists expected. So what might have really happened?

Seismological Models Are Biased, but Scientists Have a Solution
Many seismic wave models are based on an erroneous assumption about the Earth's interior. A new technique corrects this by eliminating false signals produced by models.

Revising the Displacement History of New Zealand's Alpine Fault
A reinterpretation of structural and paleomagnetic data suggests that New Zealand's Alpine Fault accommodates a far greater percentage of geologically recent plate motion than previously thought.

A New Tool to Better Forecast Volcanic Unrest
In a retrospective study of volcanic unrest at Indonesia's Kawah Ijen, a new model was able to pick up on the rising probability of eruption 2 months before authorities were aware of the risk.
