T11C:
Subduction Top to Bottom-2 I


Submit an Abstract to this Session


Session ID#: 56946

Session Description:
From top-to-bottom, many geological, geophysical, petrologic, geochemical and theoretical advances have been made in understanding the subduction zone processes and dynamics explored in 1996 in AGU Geophysical Monograph 96, “Subduction Top to Bottom”. This session, and a related Themed Issue in the online journal GEOSPHERE (http://www.geosociety.org/gsatoday/science/G354A/article.htm), are intended to revisit the topics explored 22 years ago in Monograph 96—reassessing them in light of new advances and discoveries in subduction zone research. We invite the broadest possible thematic range of contributions, including subduction-related hazards (volcanic eruptions, earthquakes and tsunamis) and resources.
