One-dimensional modeling of thermal energy produced in a seismic fault

Effect of variation of the coefficient of friction on the temperature at the level of the fault lips

“…Thermal perturbations associated with seismic slip-on faults may significantly affect the dynamic of friction and the mechanical energy release during earthquakes (Fialko, 2004). Before earthquakes, we observe more anomaly in area of earth like a deformation of rocks allows accumulation of stress energy (Gao and Crampin, 2004;Konga et al, 2017Konga et al, , 2019. According to numerous studies (Bizzarri, 2009a(Bizzarri, , 2009b(Bizzarri, , 2010Noda et al, 2009), the temperature felt generated on the fault surface is responsible to a large number of physical (Andrews, 2002;Sibson, 2003;Rice, 2006) and chemical dissipation process (Hebert et al, 2009;Kuge et al, 2010;Van Keken et al, 2003, 2011 and by consequence frictional heat on a sliding interface.…”

“…Mair and Marone (2000) show during their studies on one-dimensional heat-flow solution for frictional heating in a finite width layer that, the measure of temperature as level of fault increases systematically with friction shear and velocity. Konga et al, (2017) modelled this energy using the first principle of thermodynamic; Konga et al (2019) models the seismic energy produced at the fault lips for different law of friction, taking into account the influence of the viscosity. Their studies permit to obtain that, the temperature distribution decrease when going far from the slip zone.…”

Effect of Variation of the Coefficient of Friction on the Temperature at the Level of the Fault Lips

“…We focused more on this aspect because many previous works have shown the effect of quantities such as thermal diffusivity and thermal conductivity on the evolution of temperature and the propagation of energy in the Earth's crust. The case where cste γ = was not the subject of our analysis, since authors such as [6] [29] and [51] looked into it and showed that the temperature increases with the evolution of frictional coefficient.…”

“…During the preseismic phase (that is during the nucleation phase), an increase in temperature is generally observed with the displacement at the level of the fault. Studies make it possible to model this temperature today [6] [7]. Schotz [4] is one of the first to assess the energy balance at the level of the fault, he admitted that, this energy is equal to a sum of the energy or of the heat released in the form of seismic waves, of the work produced by friction of the fault surfaces and in the main slip zone and also the work of the gravity forces.…”

“…Mair and Marone [18] showed that temperature variations at the fault systematically increased frictional shear and velocity; thus, showing the effect of temperature variation on the state of the system. Konga et al, [6] modelled this energy using the first law of thermodynamics; and in 2019, Konga et al [7] modelled again this energy for different laws of friction and also taking into account the influence of viscosity. Their studies enabled them to obtain that the temperature distribution decreases when one moves away from the main sliding zone.…”
