The continuum of slip along the subduction megathrust


Using unprecedented data from the Nicoya Seismic Cycle Observatory, a dense seismic and GPS array directly over the active seismogenic megathrust, we mapped out nearly the total the long-term fault slip behavior, capturing through much of the seismic cycle. Slip occurs as each continuous creep, episodic slow slip, large and infrequent earthquakes, and afterslip. Characterization of this behavior is useful for assessing the boundaries of earthquake behavior, including components of major locking that were used to anticipate the location and size of the last major earthquake.
