Variation of Proportionality Between Stress Drop and Slip, With Implications for Megathrust Earthquakes

Abstract Earthquake stress drop Δσ is related to fault slip via Δσ=C⋅μ⋅DLc, where μ, D, and Lc denote shear modulus, average slip, and fault dimension. C is controlled by the system geometry, characterizes the effective stiffness of the system, and is commonly assumed to be a constant near 1. We use...
