Subduction Top to Bottom 2
Guest editors: Gray E. Bebout, David W. Scholl, Robert J. Stern, Laura M. Wallace, and Philippe Agard
From top-to-bottom, many geological, geophysical, petrologic/geochemical, and theoretical advancements have been made toward understanding subduction zone processes and dynamics. There could be huge value in increasing the number of novel collaborative combinations of the disparate techniques aimed at the same subduction-related processes. This themed issue, a follow-up to the Bebout et al.’s Subduction: Top to Bottom (American Geophysical Union, Geophysical Monograph v. 96), aims to provide assessments of recent advancements and the most promising future directions for subduction zone research, in part synthesizing our current understanding of subduction-related hazards (volcanic eruptions, earthquakes, and tsunamis).
