Abstract:
No other plate-tectonic setting has attracted such diverse, multidisciplinary research as convergent margins. Under­standing the dynamics of subduction is particularly important for realistic assessment of associated hazards such as earthquakes, tsunamis, and volcanic eruptions. A number of recent initiatives have been successful in building communities to investigate subduction processes and convey knowledge regarding subduction to other scientists, students, postdocs, and the broader public. These efforts have included synthesizing and simplifying subduction-zone science for classroom presentations and helping prepare the public for subduction-related disasters.

Tremendous advances over the past 20 or so years have been made in subduction zone science, with increasingly multidisciplinary efforts producing some of the greatest insights. In 2016, we initiated a publication effort in the GSA journal Geosphere, with a Themed Issue “Subduction Top to Bottom 2” (or “ST2B-2”) aimed at showcasing the recent advances, following up on the conceptually similar Subduction Top to Bottom (with about 35 papers) published in 1996 as an American Geophysical Union Geophysical Monograph (v96). The ST2B-2 Geosphere Themed Issue has been attracting manuscript submissions (at present approximately 80, with about 55 already published online) and is open to ALL wishing to contribute. The final deadline for submitting manuscripts is December 31, 2020.

For this Geosphere Themed Issue, we identified 17 subduction-zone science categories, arrayed as a function of increasing depth in a subduction zone, beginning with “What Goes In” and “Forces Driving Subduction.” Each of these science categories has one to three assistant guest editors (AGEs) assigned to be the contact individuals for those wanting to submit manuscripts. The evolving Geosphere ST2B-2 table of contents, and the list of AGEs, can be viewed at https://pubs.geoscienceworld.org/geosphere/pages/st2b2 and those interested in submitting a manuscript should contact one of the authors of this abstract or one of the AGEs in their respective science category (listed in the online call for papers).
