2013: Dynamics of Seismicity, Earthquake Clustering and Patterns in Fault Networks: October 9-11, 2013

Workshop Information

October 9, 2013 - 8:30am - October 11, 2013 - 1:00pm
Logo for Dynamics of Seismicity, Earthquake Clustering and Patterns in Fault Net

This workshop was held at SAMSI in Reseach Triangle Park, NC.

Objectives of the Workshop

The main goal of the workshop was to build and strengthen newly emerging links between active research groups in different scientific areas – statistics/probability, mathematics, physics, geodesy, seismology and computer science – toward achieving a solid understanding of seismicity patterns and structures and a physical theory for earthquake dynamics. The workshop highlighted the key role of the mathematical sciences in studying seismicity dynamics in relation to properties of faults and the curst as an essential component of this interdisciplinary research endeavor.

A quantitative understanding of earthquake dynamics that can improve the ability to forecast large earthquakes remains one of the major unsolved challenges in geophysics despite considerable research. This workshop aimed to achieve progress in this field by taking advantage of the newly available data sets and statistical techniques to address key questions on the properties of structural organization of seismic flow and re-examine the key statistical laws of seismicity. The workshop brought together a diverse group of scientists to review the state of the art in statistical seismology and initiate new cross-disciplinary collaborative efforts.

This SAMSI workshop was organized as a part of the international program Mathematics of Planet Earth 2013, in cooperation with the Bernoulli Society for Mathematical Statistics and Probability via the Committee on Probability and Statistics in Physical Sciences and the International Union of Geodesy and Geophysics via the Commission on Mathematical Geophysics.
