The largest recorded earthquake in United States history, a magnitude 9.2 event in 1964, occurred at the Alaska subduction zone. Some sections of this earthquake rupture zone are currently locked and accumulating strain, while other sections are creeping. This project will image the plate interface across this region to help determine the causes for the changes in slip behavior. The results will improve…
