Iceland’s Recent Eruptions Driven by Tectonic Stress
Magma flow in the magmatic dike near Grindavík was among the fastest recorded. The processes driving that flow could be at play at volcanoes in Hawaii, off the African coast, and anywhere crustal plates split apart.

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.
