Seismic Images of the Rift

Caption

SPREE array stations (red triangles) run along and across the gravity anomaly (blue) that is the rift. These stations are much closer together than the USArray ones (blue triangles). Processing the data, Shen sees a graded rather than a sharp Moho (top right), which he thinks may be due to magma trapped at the Moho or in the crust (bottom right)
