... elements. From the computed 3D stress tensor we estimate the Coulomb failure stress change (ΔCFS) on the fault plane of the event in two ways: The first with shear stresses resolved in rake direction (ΔCFS slip ) and the second using the maximum shear stress (ΔCFS max ) on the plane. The ΔCFS slip values...

Increasing and decreasing normal load during residual section make significant changes in corresponding AE signals. 1 INTRODUCTION Previous researches have addressed...
