Fall AGU Session T18: Observations, Interpretations, and Implications of Slow Slip, Non-Volcanic Tremor, and Associated Phenomena

Dear Colleagues,

We'd like to encourage you to submit an abstract for Fall AGU session T18, "Observations, Interpretations, and Implications of Slow Slip, Non-Volcanic Tremor, and Associated Phenomena". This session aims to explore the many different slow-slip and tremor phenomena that have recently been discovered in an ever-increasing number of localities. We look forward to your contribution to this important and timely topic.

Abstract submissions are due September 6, 2007:

Best Regards

Satoshi, Hitoshi, John, and Justin

T18, "Observations, Interpretations, and Implications of Slow Slip, Non-Volcanic Tremor, and Associated Phenomena".

Conveners: J. Rubinstein (U. Washington), S. Ide (U. Tokyo), H. Hirose (NIED), & J. Townend (Victoria U. of Wellington)

Aseismic fault slip, non-volcanic tremor, and other low-frequency seismic phenomena have been observed in a variety of tectonic environments, most notably subduction zones but also within the strike-slip San Andreas Fault zone and beneath the island of Hawaii. In the Cascadia and southwest Japan subduction zones, in particular, the spatiotemporal coincidence of tremor and slow slip suggests a strong relation between these phenomena, but our understanding of the underlying physical processes is incomplete and other locations exhibit either slow slip or seismic tremor but not both. In addition to addressing the long-standing scientific goal of understanding fault mechanical processes, including the generation of megathrust earthquakes in subduction zones, recent observations have significant policy implications based on the suggestion that seismicity and seismic hazard may increase following slow slip activity.

This session seeks presentations that shed light on the mechanics of slow slip, non-volcanic tremor, and associated phenomena, as well as the hazard implications posed by these processes. In particular, we seek contributions that explore this burgeoning field of research using new techniques, new observations, and innovative modeling. We also welcome studies that address regional variations in the occurrence and characteristics of these phenomena.
