Characteristic scales of earthquake rupture from numerical models

Characteristic scales of earthquake rupture from numerical models

Numerical models of earthquake rupture are used to investigate characteristic length scales and size distributions of repeated earthquakes on vertical, planar fault segments. The models are based on exact solutions of static three-dimensional (3-D) elasticity. Dynamical rupture is approximated by allowing the static stress field to expand from slip motions at a single velocity. To show how the ...

Standards for Documenting Finite-Fault Earthquake Rupture Models

In this article, we propose standards for documenting and disseminating finite-fault earthquake rupture models, and related data and metadata. A comprehensive documentation of the rupture models, a detailed description of the data processing steps, and facilitating the access to the actual data that went into the earthquake source inversion are required to promote follow-up research and to ensu...

Characteristic spatial and temporal scales unify models of animal movement.

Animal movements have been modeled with diffusion at large scales and with more detailed movement models at smaller scales. We argue that the biologically relevant behavior of a wide class of movement models can be efficiently summarized with two parameters: the characteristic temporal and spatial scales of movement. We define these scales so that they describe movement behavior both at short s...

The Mechanics of Earthquake Rupture

Earthquake Nucleation and Rupture at a Range of Scales : Laboratories , Gold Mines , and Subduction Zones

We measured spectral and time-domain properties of seismic events over a size range that spans magnitudes M r -2 to 8 in order to study earthquake source processes. In addition, we conducted laboratory experiments to study interseismic behaviors that can influence earthquake nucleation and we developed a model of eathquake rupture to explain the scaling behaviors we observe. To bridge the scale...
