From: Seismic imaging of slab metamorphism and genesis of intermediate-depth intraslab earthquakes
Across-arc vertical cross-sections of intraslab earthquakes and dehydration loci in the slabs. a Tohoku and b eastern Aleutian subduction zones. Dehydration loci of metamorphosed crust and serpentinized mantle are indicated by the green and red lines, respectively. Red broken lines and red dotted lines are those based on the antigorite reaction boundaries of Ulmer and Trommsdorff (1995) and Wunder and Schreyer (1997), respectively. Blue dots are earthquakes. Thermal structure is shown as isothermal contours. (After Yamasaki and Seno, 2003)
