Fig. 7From: Phreatic eruptions and deformation of Ioto Island (Iwo-jima), Japan, triggered by deep magma injectionA comparison of observed crustal deformation (red arrows) with that calculated (blue arrows) by the best-fit sill-like deformation source (gray rectangles) of a, b before and c, d after the beginning of the eruption of April 29, 2012. Red stars show eruption points. Displacement vectors are relative to the 0603 station of GSI (see Fig. 1a for location)Back to article page
