Two AGU Session Announcements

Date: 07/23/2014

Dear SCEC Community,

The deadline for the 2014 AGU Fall Meeting session abstract submission is coming up in just a couple of weeks (August 6). As such, we are continuing to receive a great number of requests to send out session announcements to inform, invite, and remind potential abstract submitters in advance of this deadline. Included below are 2 more of these announcements -- sessions 3576 and 3668.

If you plan to attend AGU, please take a moment to review these announcements.

Thank you!

======================= Session 3576 ===================

Dear Colleagues,

Please consider the following session for AGU!

Earthquake Energy Budgets: Geological, Laboratory and Geophysical Constraints (# 3576)

When an earthquake occurs, elastic strain energy is released to overcome frictional resistance to slip and in the creation of fault surfaces, seismic waves, and topography. Tectonic setting, fault friction, fault shape, and rheology all influence energy release and characterizing this influence is fundamental our knowledge of earthquake physics and fault mechanics. In addition, energy controls the recurrence, speed, and extent of earthquakes and the intensity of ground motions, so understanding energy release is fundamental to mitigating seismic hazard. We invite abstracts that examine earthquake energy across spatiotemporal scales, using experimental, numerical and analytical approaches. We welcome contributions that attempt to quantify energy components from experimental, geological and geophysical data, focus on relationships between energy and earthquake/fault parameters, and critically consider energy through modeling. Studies of diverse earthquake sources from seismological data and in the field and lab, including megathrust, crustal, volcanic, deep and non-volcanic tremor and induced seismicity, are encouraged.

======================= Session 3668 ===================

Dear SCEC Community,

Please consider submitting an abstract to session #3668 at the fall meeting of the AGU:

Title: Foreshocks and their Predictive Value: Recent Observations, Lab Experiments, Numerical Simulations, and Prospective Forecasting Experiments

Description: Foreshocks remain the most informative indicator of a damaging earthquake in the near term. Over the last two decades, the hypothesis has gained popularity that foreshocks are nothing but earthquakes followed by a larger aftershocks, suggesting a common mechanism for most tectonic earthquakes and a predictive value that is limited by generic Omori-Utsu clustering. Recent observations, experiments and numerical models of foreshock activity, however, have been claimed to challenge this notion. For example, slow slip events have been inferred to drive accelerating foreshock activity; stress drops of foreshocks and aftershocks have been claimed to systematically differ; and a variety of foreshock behavior has been observed in recent laboratory experiments and numerical simulations. To shed new light on the nature and predictive value of foreshocks, we solicit presentations from all areas of earthquake science, including induced seismicity. We seek insights from recent observations, lab experiments, earthquake-cycle simulations, and prospective forecasting experiments.
