The reality of the scaling law of earthquake-source spectra?
Attempts to build a “constant-stressdrop” scaling of an earthquake-source spectrum have invariably met with difficulties. Physically, such a scaling would mean that the low-frequency content of the spectrum would control the highfrequency one, reducing the number of the parameters governing the time history of a shear dislocation to one. This is technically achieved through relationships of the...
متن کاملScaling Relations for Earthquake Source Parameters and Magnitudes
A data set of 41 moderate and large earthquakes has been used to derive scaling rules for kinematic fault parameters. If effective stress and static stress drop are equal, then fault rise time, z, and fault area, S, are related by z = 16S1/2/(7~3/2~8), where ,8 is shear velocity. Fault length (parallel to strike) and width (parallel to dip) are empirically related by L = 2W. Scatter for both sc...
متن کاملSource time function properties indicate a strain drop independent of earthquake depth and magnitude.
The movement of tectonic plates leads to strain build-up in the Earth, which can be released during earthquakes when one side of a seismic fault suddenly slips with respect to the other. The amount of seismic strain release (or 'strain drop') is thus a direct measurement of a basic earthquake property, that is, the ratio of seismic slip over the dimension of the ruptured fault. Here the analysi...
متن کاملScaling of earthquake fault parameters
The long-standing conflict between the predictions of elastic dislocation models and the observation that average coseismic slip increases with rupture length is resolved with application of a simple displacement-depth function and assumption that the base of the seismogenic zone does not result from the onset of viscous relaxation, but rather a transition to stable sliding in a medium that rem...
متن کاملScaling law for the critical function of an approximate renormalization
We construct an approximate renormalization for Hamiltonian systems with two degrees of freedom in order to study the break-up of invariant tori with arbitrary frequency. We derive the equation of the critical surface of the renormalization map, and we compute the scaling behavior of the critical function of one-parameter families of Hamiltonians, near rational frequencies. For the forced pendu...
