Session at SSA meeting in Pasadena: How reliable are reconstructions and models of surface-rupturing earthquakes?

The SSA 2015 meeting will take place in Pasadena, CA, from 21-23 April. As always, there will be plenty of interesting things for paleoseismologists. Scott Bennett asked me to advertise the following session that deals with a topic most of us will find highly important:

How Reliable Are Reconstructions and Models of Surface-Rupturing Earthquakes?

Abstract deadline is 9 January, 2015.

Historic surface-rupturing earthquakes have demonstrated a potential for complex, discontinuous rupture traces. With this in mind, how well do reconstructions and models of past ruptures from paleoseismology, geomorphologic slip-rate studies, or finite fault models and forecasts of future surface-rupturing earthquakes [e.g. UCERF3 (CA), WGUEP (UT), J-SHIS (Japan)] realistically describe the complexity of surface ruptures? Are earthquake magnitudes and rupture lengths from empirically-based models consistent with individual field-based observations (e.g. timing, displacement) of past events)? This session will highlight advancements in earthquake science that improve our understanding of fault segmentation, rupture dynamics, distributed deformation, along-strike and down-dip fault-slip gradients, and related seismic hazard topics. We welcome abstracts from a wide spectrum of scientists, including paleoseismologic studies of Quaternary-active structures, detailed studies of modern ruptures, and dynamic or simulator models of rupture scenarios. We invite discussion of new, innovative approaches that characterize active structures and earthquakes using field-based techniques, computer modeling, and remote sensing. The goal of this session will be to consider ways to improve the documentation of past earthquakes and to advance our estimates of earthquake probabilities.
