Volatile recycling at the Lesser Antilles Arc: Processes and consequences

Frank Kruger, Andreas Rietbrock, Catherine Rychert, Nicholas Harmon & Jenny Collier
Subduction zones are the prime regions where water is exchanged between the solid Earth, oceans and atmosphere. Yet, water transport through subduction is only partially understood. In this project, we target the Lesser Antilles Arc, one of only two zones that subducts lithosphere formed at the slowly spreading Mid-Atlantic Ridge. Atlantic lithosphere is more hydrated, especially in the mantle part, than lithosphere consumed at Pacific and Indian Ocean trenches, making it a key endmember to...

INL Seismic Monitoring Program

Idaho National Laboratory
The INL Seismic Monitoring Program provides earthquake data and staff expertise in support of requirements set forth by Presidential executive orders, Department of Energy (DOE) directives, orders and standards, and the Nuclear Regulatory Commission for seismic safety of workers and the public with regard to nuclear related operations at INL. The program supports safety of operations through continuous monitoring of earthquake activity, the development of INL seismic design criteria, assessments of seismic hazards for existing...

Subduction Reversal and the Ontong Java Plateau

Nicholas Harmon, Catherine Rychert, Derek Keir, Brian Savage & Yang Shen
Seismic deployment for passive imaging in Papua New Guinea to image the downing slabs in the region to understand the role of the Ontong Java Plateau in subduction reversal. The array consists of 6 Guralp 3ESPD and 2 Guralp 3TD.
