Organized by: U.S. Geological Survey (USGS) and Cascadia Region Earthquake Science Center (CRESCENT)
We invite you to join us for a week of Subduction Zone Science in Portland, Oregon, January 12 – 15, 2027. The U.S. Geological Survey (USGS) and Cascadia Region Earthquake Science Center (CRESCENT) are organizing sessions highlighting new research, hazard products, and user needs from around the nation and within the Cascadia Subduction Zone.

This Subduction Zone Science Week will convene the nation’s leading subduction zone researchers, federal scientists, engineers, and community partners to share knowledge across earthquakes, tsunamis, volcanoes, landslides, and cascading hazards. The goals of this week are to (1) foster collaboration between subduction zone and multi hazard researchers, (2) bridge gaps, and increase communication among subduction zone research groups, and (3) identify and encourage synergistic collaborative activities in U.S. and global subduction zones.
The first two days (January 12-13) are focused on USGS Subduction Zone Science priorities with sessions highlighting new research, data, and scientific questions across a broad range of natural hazards in subduction zone systems within the U.S. and globally. Topics will include subduction zone paleoevent characterization, monitoring and early warning, modeling natural hazards and their impacts, external engagement, and hazard and risk communication.
The second two days (January 14-15) 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.
This meeting is open to anyone interested in subduction zone science, and we encourage participation from researchers, agency partners, and end-users working in a range of subduction zone systems. Register now and be sure to check for updates and announcements on our event webpage.
Looking forward to seeing you there,
Lydia Staisch (lstaisch@usgs.gov) and Diego Melgar (dmelgarm@uoregon.edu)
