University of Washington oceanographers are working with a local company to develop a simple new technique that could track seafloor movement in earthquake-prone coastal areas.
“This effort will really change the information we have at our disposal for understanding the seismic properties of subduction zones,” said Emily Roland, a UW assistant professor of oceanography and one of nine principal investigators on the project.
Researchers analyzing data from ocean-bottom seismometers off the Washington-Oregon coast tied a series of underwater landslides on the Cascadia Subduction Zone to a 2012 magnitude-8.6 earthquake in the Indian Ocean — more than 8,000 miles away. These underwater landslides occurred intermittently for nearly four months after the April earthquake.

Pacific Northwest Seismic Network, USGS and partners launch West Coast earthquake early warning system
The first Pacific Northwest pilot users of the system are Bothell, Wash.-based RH2 Engineering, which will use the alerts to secure municipal water and sewer systems so these structures remain usable after a major quake.
Associate Professor and M9 Project investigator, Joe Wartman, recently published an op-ed on the interface between natural hazards and people. The opinion article, titled “What we’ve learned from the deadly Oso, Washington landslide two years on”, can be accessed here.Read more

“Congress is finally waking up to the need for better earthquake preparedness in the Pacific Northwest.”
Register-Guard opinion piece
Eugene Mayor Kitty Piercy – “A can-do, action-oriented approach to individual preparedness, a civic emphasis on resilience, and public and private investment in earthquake early warning are all steps that will keep us safer.”
Professor Tim McDaniels (UBC) will speak about “A yawning governance gap that degrades regional infrastructure resilience” at the M9 All-Hands Meeting on Tuesday, February 9. M9 Meetings are held from 2:30-3:30 PM in Molecular Engineering room 115.
