Deep earthquakes triggered by the olivine-poirierite transition
Seismicity decreases with depth because elevated confining pressure prevents frictional sliding of faults. However, seismicity tends to increase with depth in the mantle transition zone (depths of 410−600km). It has been ...

Atlantic current system could be weakening faster than expected
The Atlantic current system, or more formally the Atlantic Meridional Overturning Circulation (AMOC), is more likely to weaken than previously thought. That's the conclusion of a new study published in the journal Science ...
Waikīkī faces escalating threat of sewage-contaminated flooding as sea level rises
A new study by University of Hawai'i at Mānoa researchers revealed that Waikīkī is facing a fundamental shift in flood hazards as sea levels rise—transitioning from a flooding that is driven primarily by rainfall to events ...

Combining seismic and space data to detect calving in Greenland glaciers
When the edge of a Greenland glacier breaks off into the sea to become an iceberg, can a global seismic network "hear" it? The answer is yes—but only if the event is a large one. And it helps to pair the resulting surface ...
