The system discussed in this study. Before the onset of slip (\(t < 0\)), there is no heat flow. During slip (\(0 \le t \le t_{{\text{s}}}\)), a fault zone of width \(2l\) deforms homogeneously at constant slip rate \(v_{{\text{s}}}\) under time-dependent shear stress \(\tau \left( t \right)\) to supply heat to the fault zone, which generates heat flow parallel to the \(x\) direction. After slip ceases (\(t_{{\text{s}}} < t\)), heat flow continues and contributes further to the temperature change
