Rupture styles linked to recurrence patterns in seismic cycles with a compliant fault zone

A Rate‐, State‐, and Temperature‐Dependent Friction Law With Competing Healing Mechanisms

“…The resulting complex mechanical response can be captured by empirical friction laws that employ a state variable to represent structural evolution within the fault zone (Chester, 1994; Dieterich, 1979, 1981; Ruina, 1983). The rate‐ and state‐dependent friction formulations are key to representing all stages of the seismic cycle with different rupture styles (Barbot et al., 2012, 2018, 2020, 2021; Lapusta & Barbot, 2012; Lapusta & Rice, 2003; Liu & Rice, 2005; Mei, Barbot, & Wu, 2021; Nie & Barbot, 2021; Sathiakumar & Barbot, 2021; Shi et al., 2020; Veedu & Barbot, 2016) and recurrence patterns (Cattania, 2019; Nie & Barbot, 2022).…”

The role of three-dimensional fault interactions in creating complex seismic sequences

“…Seismic events start to appear when seismogenic width W is larger than L ∞ . Studies have shown that on a single fault, a complex seismic sequence of full and partial ruptures can emerge when the ratio between W and L ∞ is sufficiently large (Barbot, 2019;Cattania, 2019;Heimisson, 2020;Nie and Barbot, 2022). Cattania (2019) found that for a 1-D fault, the minimum ratio to generate two and more events per cycle is ∼ 10.…”

The Spectrum of Fault Slip in Elastoplastic Fault Zones

“…These on-fault characteristics controlling the spectrum of slip are investigated mostly with homogeneous elastic bulk. Heterogenous bulk with a low velocity zone near the fault may generate slip complexity Thakur et al 2020;Nie & Barbot 2022). Also, a recent study by Collettini et al (2022) explains the observation of distributed microseismicity through a conceptual model of distributed ductile deformation in the bulk.…”
