Frictional coefficient on faults in a seismogenic region inferred from earthquake mechanism solutions

Frictional weakening and slip complexity in earthquake faults

Previous work has shown that velocity-weakening friction produces slip complexity in simple dynamical models of earthquake faults ( Carlson and Langer, 1989). Rere I show that a different type of dynamical instability, caused by slipweakening friction, also produces slip complexity. The deterministically chaotic slip complexity produced by slip-weakening friction in a simple one dimensional mod...

Stress-Breakdown Time and Slip-Weakening Distance Inferred from Slip-Velocity Functions on Earthquake Faults

We estimate the critical slip-weakening distance on earthquake faults by using a new approach, which is independent of the estimate of fracture energy or radiated seismic energy. The approach is to find a physically based relation between the breakdown time of shear stress Tb, the time of peak slip-velocity Tpv, and the slip-weakening distance Dc, from the time histories of shear stress, slip, ...

Earthquake Ruptures on Rough Faults

Natural fault surfaces exhibit roughness at all scales, with root-mean-square height fluctuations of order 10−3 to 10−2 times the profile length. We study earthquake rupture propagation on such faults, using strongly rate-weakening fault friction and offfault plasticity. Inelastic deformation bounds stresses to reasonable values and prevents fault opening. Stress perturbations induced by slip o...

Frictional Characteristics in Deeper Part of Seismogenic Transition Zones on a Subduction Plate Boundary

Study on the Seismogenic Mechanism of the Earthquake Mw6.9 in 2014 in the Aegean Sea Seismic Cone

In accordance with the Seismo-Geothermics theory about methods of intracrustal strong earthquake and volcano prediction, we use the ANSS earthquake catalogue from the Northern California earthquake data center and the EMSC earthquake catalogue from the European-Mediterranean Seismological Centre to study the seismic activities of the Turkish Branch Seismic Cone in the Mediterranean Seismic Cone...
