Water-rock reactions in some hydrothermal systems produce both hydrogen, which could be tapped for clean energy, and alkaline solutions that could help draw down atmospheric carbon dioxide.

Subducted Seamounts May Lead to Larger Earthquakes
New findings show that underwater mountains may increase friction along subduction zones, building up stress and making larger ruptures more likely.

Low-Frequency Quakes Have Modest Effect on Slow Earthquake Cycle
Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.

Talc May Make Mexico’s Subduction Zone More Slippery
Production of the weak, water-bearing mineral at the interface between the Cocos and North American Plates could contribute to the occurrence of poorly understood episodic tremor and slow slip.
