Extended Data Fig. 1: Spatiotemporal variations in megathrust slip and locking used in synthetic models of repeating earthquake cycles.
From: Interseismic secondary zone of subsidence during earthquake cycles in subduction zones
a, The temporal variation. Slip deficit accumulated in one cycle is fully recovered by the next earthquake. A longer recurrence time is followed by a larger coseismic slip. b, Downdip distribution of megathrust locking or slip described using a bell-shape function53. c, Map views of the spatial variation. For 3-D synthetic tests, we assume that a shorter recurrence interval is associated with a shorter rupture (as well as a smaller slip). Here the line of symmetry of the synthetic rupture is the equator. The three 3-D models feature full locking for 1°, 5°, or 10° along strike, plus a gradual transition to 0 over 0.5° following a sine function. In 2-D models, the downdip distribution is the same as in the 3-D models, but there is no along-strike variation.
