2025 USGS Subduction Zone Science Workshop

By Subduction Zone Science

Subduction Zone Science Workshop

January 8–9, 2025 Seattle, Washington

The U.S. Geological Survey invites you to a free Subduction Zone Science meeting in Seattle at the University of Washington January 8–9, 2025.

The U.S. Geological Survey (USGS) is hosting an in-person Subduction Zone Science meeting at the University of Washington from January 8–9, 2025 as part of a week-long series of subduction zone activities from January 7–10 organized by the USGS and our Academic partners. Links to additional information on events on January 7th and 10th are provided below. 

The 2025 USGS Subduction Zone Science meeting is organized around five themes:

  1. Community-engaged Subduction Zone Science 
  2. Earthquake Hazards and Impacts in Subduction Zones 
  3. Structure and Deformation in Subduction Zones 
  4. Earthquake Recurrence and Process in Subduction Zones 
  5. Volcano Recurrence, Process, and Hazards in Subduction Zones

Each session will include invited keynote talks, as well as several short-format talks that can be requested in the signup form below. We will also host an open lightning talk and poster session for any data, research, product, or initiative related to Subduction Zone Science within or beyond the existing themes. 

This meeting is open to everyone, and we encourage participation from individuals across Academic, State and Local, Tribal, Private, and other Federal institutions, in addition to the USGS. The goals of this meeting are to share new data, science, and hazards information across subduction zones, and provide opportunities to build new connections and collaborations across a diverse range of subduction zone science and engineering problems.

Additional information on adjacent meetings coming soon.

 

Organizing Committee:

Erin Wirth, alex grant, Lydia Staisch, Fred Pollitz, and Joan Gomberg

If you would like to host a special interest group meeting during the lunch break, please contact Erin Wirth for more information. 

1:30 – 2:00 Open Lightning Talks

Contributions are welcome on any subduction zone science topic, including updates from proposed and ongoing initiatives, new and proposed datasets, and recent findings.

2:00 – 4:00 Community-engaged Subduction Zone Science 

Highlighting a broad swatch of physical science, hazard and risk modeling, communication research and tools, or any other research/products driven by, and coproduced with, the affected communities. 

4:00 – 6:00 Open Poster Session (HUB Room 145)

Contributions are welcome on any subduction zone science topic, including updates from proposed and ongoing initiatives, new and proposed datasets, and recent findings.

Thursday, January 9

Characterization of the physical form, properties, and deformation of subduction zone systems. Topics may include on- and off-shore geodesy, geomorphology, geophysics, fault mapping, and model development.

10:10 – 10:30 Break

10:30 – 12:00 Earthquake Recurrence and Process in Subduction Zones 

Characterization of earthquake rates and processes acting on and off faults within subduction zone systems. Topics may include large and small magnitude earthquake observation and modeling, paleoseismology, and recurrence rate constraints and models
