Subduction Zone Science Week

Meeting Goals

Subduction Zone Science Week will convene the nation’s leading subduction zone researchers, federal scientists, engineers, and community partners to integrate global and Cascadia-focused knowledge across earthquakes, tsunamis, volcanoes, landslides, and cascading hazards.

Subduction Zone Science Week is co-organized by the USGS and CRESCENT to focus broadly on the subduction zone natural hazards and community resilience. The goals are to:

  • Foster collaboration between subduction zone and multi hazard researchers;
  • Bridge gaps, and increase communication among subduction zone research groups; and
  • Identify and encourage synergistic collaborative activities in U.S. and global subduction zones.

The first two days are aimed towards USGS Subduction Zone Science priorities and will highlight a broad range of natural hazards in subduction zone systems and how science, monitoring, and forecasting can enhance resilience within the U.S. and globally. Topics will include subduction zone paleoevent characterization, hazard and risk modeling of natural disasters, cascading hazards, monitoring and warning systems, external engagement, and hazard and risk communication.

The second two days focus on the Cascadia Subduction Zone, where CRESCENT has accelerated targeted research, community engagement, and workforce initiatives.The Cascadia program is organized around questions rather than disciplines. Each session leads with a hazard or risk question and brings in the science that answers it, alongside the people who use that science to make decisions.

The knowledge synthesized during Subduction Zone Science Week will directly inform the tools, models, and warning systems that protect millions of people living in Alaska, the Pacific Northwest, the Caribbean, and other U.S. regions exposed to subduction zone hazards.

Subduction Zone Science Week is supported by the U.S. Geological Survey under Grant/Cooperative Agreement No. G26AC00314-00 and by NSF Cooperative Agreement #2225286

Poster Session Details

There are three formal poster sessions during SZS Week:

Tuesday, January 12, 2027, 4:30-6:30 pm

Thursday, January 14, 2027, 10:00-11:30 am & 4:30-6:30 pm

There will also be time to visit posters during breaks.

Poster session logistics: 

  • Poster dimensions should be a maximum of 8′ (width) by 4′ (height).  
  • You will have the opportunity to hang your poster in the poster session space on Tuesday, during the lunch break or Thursday, upon arrival.
  • Each poster will be assigned a number that corresponds to a designated location. Staff will be on hand to help you find your space. Push pins/ tape will be provided for you to hang your poster. 
  • You may leave your poster up overnight until the sessions end and remove it on Wednesday at 12:00 pm or Friday at 12:00 pm. All posters need to be removed before 1:00 pm on Friday.
