The 2011 Tohoku Earthquake presented unique circumstances that permitted access to a fault that recently slipped tens of meters and installation of a subseafloor observatory for time-sensitive measurements. These data provide insight into the stress level on the megathrust fault during slip and characterize the rapid changes in properties that may influence future events. The results are crucial for building a full physical model of the earthquake cycle and for characterizing tsunami hazard.
