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.

Rift-to-Ridge: Mid-Atlantic Ridge Segments Imprinted During Rifting
A new seismic study shows that magmatism along the eastern North American rift margin was segmented, and that rift discontinuities influence formation of fracture zones along the Mid-Atlantic Ridge.
