Yet, their remoteness often leaves them undetected. Recent seismic studies at the East Pacific Rise (EPR) 9{\\deg}50'N-one of the most dynamic ridge segments, imaged the detailed architecture of the shallowest magma lens, but no data-constrained model yet explains how magma accumulates, migrates, or triggers eruptions. Similarly, the formation of oceanic crust remains poorly understood.
