Illuminating a Contorted Slab With a Complex Intraslab Rupture Evolution During the 2021 Mw 7.3 East Cape, New Zealand Earthquake

Abstract: Complex fault configurations and heterogeneous fault conditions, that is, stress and strength states, govern earthquake rupture development and propagation (

“…The hypocenter relocated by Okuwaki et al. (2021) is at 72 km, which is below the lower plane of the double seismic zone and is in the slab mantle in this region (Figure 3e). There is also a swarm of aftershocks from 50 to 80 km, most of which are in the regions with positive coulomb stress change (Figure 3b).…”

“…(a) The horizontal cross‐section (at depth of 12 km) of Coulomb stress change projected to the fault orientation corresponding to Subevent 2 (Nodal Plane 1, dip = 42°, rake = −120°, and strike = 29°) caused by Subevent 1 (Nodal Plane 1, dip = 80°, rake = 59°, and strike = 43°) based on the subevent inversion results of Okuwaki et al. (2021); The focal mechanisms and the locations of the two subevents are shown as the green beach balls in (a and b). The black beach balls show the focal mechanisms of the background seismicity from 1976/1/1 to 2021/1/1 (Global Centroid Moment Tensor).…”
