Insights into dike nucleation and eruption dynamics from high-resolution seismic imaging of magmatic system at the East Pacific Rise
Models of magmatic systems suggest that the architecture of crustal magma bodies plays an
important role in where volcanic eruptions occur, but detailed field observations are needed …
