2025 USGS Subduction Zone Science Meeting

By Subduction Zone Science

Subduction Zone Science Meeting

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.

Register for Meeting

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. The meeting is organized around five themes:

  1. Community-Focused Subduction Zone Science 
  2. Cascading Hazards and Impacts 
  3. Structure and Deformation in Subduction Zones 
  4. Earthquake Recurrence and Processes
  5. Understanding, Monitoring, and Communicating Volcanic Hazards

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.

If you are interested in attending this meeting, please register by Wednesday, November 13.

8:30 – 8:50 Welcome, Meeting Goals, and Logistics

8:50 – 10:10 Cascading Hazards and Impacts

Topics may include direct effects of earthquakes and volcanoes within subduction zone systems as well as short- and long-term secondary impacts, including tsunami, landslides and lahars, liquefaction, damage to the built environment, and the interaction of these hazards.  

Invited Speakers:

10:30 – 12:00 Understanding, Monitoring, and Communicating Volcanic Hazards in Subduction Zones

                  This session will highlight topics that advance our understanding of volcanic hazards, including the magmatic systems that drive eruptions, novel techniques to monitor volcanoes, and communicating volcanic hazards to communities at risk.  

                  Invited Speakers:          

  • Cheryl Cameron (Alaska Division of Geological & Geophysical Surveys)
  • Alex Iezzi (U.S. Geological Survey)
  • Brandon Schmandt (University of New Mexico)

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-Focused 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. 

Invited Speakers:

  • Amina Meselhe (Oregon State University)
  • Jenny Riker (U.S. Geological Survey)
  • Jenna Tilt (Oregon State University)

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

8:30 – 8:40 Welcome and Announcements

8:40 – 10:10 Structure and Deformation in Subduction Zones 

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.

Invited Speakers:

  • Jessica DePaolis (Virginia Tech)
  • Eric Lindsey (University of New Mexico)
  • Nathan Miller (U.S. Geological Survey)

10:10 – 10:30 Break

10:30 – 12:00 Earthquake Recurrence and Processes

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.

Invited Speakers:

  • Brian Sherrod (U.S. Geological Survey)
  • Drake Singleton (U.S. Geological Survey)

12:00 Adjourn to the poster hall (HUB Room 145)
