Session 1. Active faults: reconciling short and long terme observations

Conveners: A. Copley, J. Hollingsworth, L. Audin

A major unsolved problem in the geosciences concerns the mechanisms and processes which govern how earthquake cycles produce topographic and geological structures. Many of the planet's major morphological features, such as mountain ranges and basins, were formed by faulting. However, the mechanisms by which earthquake cycles produce geological structures, and the material properties that control this behaviour, are sources of considerable debate. Quantitative data on fault and off-fault strain rates spanning various time-scales is critical for developing and testing physical models of geological deformation. Nevertheless, quantifying the rate and style of fault slip over timescales from seconds to millions of years is a challenging task.

Documenting fault slip at short time-scales can be achieved through geodetic observation and seismology, and over medium-to-long time-scales through paleoseismology, tectonic geomorphology and structural geology. However, the process reconciling data across these different approaches to give a coherent view of fault behavior is currently in its infancy. We therefore seek contributions which investigate how faults slip over a range of time-scales (utilizing a variety of methods, including geodesy, seismology, geochronology, geomorphology, or structural geology).

We particularly welcome contributions which seek to use such data to understand the mechanical behavior of the crust over geological time-scales, and the formation of geological structures.
