image: Cross sections of hypocenters superposed on thermalmodels. Enlarged view of cross section C-C? to show the seismic belt. Yellow and black dots are the actual hypocenters. The solid and dashed gray curves illustrate the slab surface and Moho, respectively. This material relates to a paper that appeared in the Jan. 11, 2017, issue of Science Advances, published by AAAS. The paper, by S.S. Wei at Washington University in St. Louis, Mo., and colleagues was titled, 'Slab temperature controls on the Tonga double seismic zone and slab mantle dehydration.' view more
