Fig. 5: Comparisons between the finite-fault and back-projection results, and the three stress release models.
a Comparisons between the finite-fault inversion (low-frequency) and back-projection (high-frequency) results for the earthquake doublet. The along-strike moments of the finite-fault model (squares) are normalized. The circles and diamonds are the back-projection results of the first and second events, respectively30. The light blue circles mark the geometric changes between S2 and S7 and between S8 and S9, where ruptures were blocked and high-frequency signals were radiated (Fig. 2d). b Simple linear slip-weakening model, where the final stress equals the frictional stress. Db is the balanced position. c Undershoot model, where the final stress is greater than the residual stress and the radiated efficiency is greater than that in (b). d Overshoot model, where the final stress is lower than the residual stress and the radiated efficiency is lower than that in (b).
