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.

Earthquakes Have Preparatory Stage Years Before Rupture
Tidally induced seismicity increased locally before the 2019 Ridgecrest earthquake, suggesting that fault sensitivity to stress increases in the years immediately before large earthquakes.
