Collaborative Research: Follow on to Seafloor Optical Fiber Strainmeters for the Detection — NSF Award to University of California

The Cascadia subduction zone lies offshore Oregon and Washington. This region is known for slow-slip events, where the plates gradually slip past each other slowly over days, weeks, or months. Onshore instrumentation can detect slow slip, but seafloor instrumentation is needed to monitor the full subduction zone. This

AbstractThe Cascadia subduction zone lies offshore Oregon and Washington. This region is known for slow-slip events, where the plates gradually slip past each other slowly over days, weeks, or months. Onshore instrumentation can detect slow slip, but seafloor instrumentation is needed to monitor the full subduction zone. This is important because slow slip may increase the chance of triggering a great megathrust earthquake and tsunami. This project will extend a time series of seafloor optical fiber str
