2025 USGS Subduction Zone Science Meeting

Agenda for the U.S. Geological Survey-hosted Subduction Zone Science meeting in Seattle at the University of Washington from 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. 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 (listed below), as well as several short-format talks highlighting a range of new products, observations, and datasets related to subduction zone science, hazards, and impacts. We will also hold a poster session with over 90 submissions on Wednesday January 8th to include far more new research and perspectives on subduction zone science.

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.

 

Organizing Committee:

Erin Wirth, alex grant, Michelle Coombs, Joan Gomberg, Emily Johnson, Fred Pollitz, Lydia Staisch, Wes Thelen, and Aaron Wech.

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

8:50 – 10:15 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:

  • Audrey Dunham (U.S. Geological Survey)

10:15 – 10:40 Break

10:40 – 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 (Rice University)

12:00-2:00 Lunch (On your own. See logistics page for suggestions.)
Optional: Offshore Observations Special Interest Group meeting (contact: Will Wilcock)

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

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)
  • Nate Wood (U.S. Geological Survey)

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

Poster presentations on a wide range of subduction zone science topics, including updates from proposed and ongoing initiatives, new and proposed datasets, and recent findings.

Refreshments will be provided by the Pacific Northwest Seismic Network (PNSN), as well as a cash bar.


Thursday, January 9
University of Washington, Husky Union Building (HUB) Lyceum (room 160)

8:30 – 8:35 Welcome and Announcements

8:35 – 10:00 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)

10:00 – 10:20 Break

10:20 – 11:45 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)
  • James Biemiller (U.S. Geological Survey)

11:45 Closing and adjourn to the poster hall (HUB Room 145)


Friday, January 10
