Scaling of Earthquake-Source Parameters


​​How do earthquake-rupture dimensions grow with increasing magnitude? Understanding earthquake source-scaling behavior provides important input for reliable seismic hazard analysis, studies on earthquake mechanics and for simulating rupture dynamics.

The surge in earthquake-source imaging studies during recent years- captured by the SRCMOD database - allows investigating more deeply this fundamental topic on a global scale.  We examine source-scaling properties in different faulting regimes, illuminating their variability and control by tectonic settings such as seismogenic depth, fault-dip, and faulting mechanisms.
