... of the three systems (plastic–viscous and frictional–viscous) are wrong, and the remaining one (brittle–plastic) is an oversimplification. Unfortunately, despite a correct emphasis on the importance of viscoelasticity, the comment contains many conceptual errors, rendering its contents more misleading than...

... in the rock record. Due to the frictional resistance of faults, heat is rapidly generated during coseismic slip, leading to temperature spikes ( Rowe and Griffith, 2015 ). Utilizing this relationship, we identified evidence of frictional heating during earthquakes through the creeping section of the SAF...

... with the spatiotemporal heterogeneity of stress produced by previous earthquakes on the same fault, we use multicycle simulations under the rate and state (RS) friction law. We adopt a one‐way coupling from multicycle simulations to dynamic rupture simulations; the quasidynamic solver QDYN is used to nucleate the seismic...

The authors considered only the viscous dissipation as the damping mechanism in their model, whereas another damping mechanism is the contact line friction, when a static contact angle hysteresis is taken into account ( Rozhko, 2020 ). Furthermore...
