AGU 2005 fall meeting - special session   San Francisco, 2005-12-07 15:55:00 - 2005-12-12 15:55:00

Geophysical model optimisation: It is now standard practice to use sophisticated computer models to study complex processes in the Earth. Examples include 3D wave-propagation codes in seismology, flow models in core and mantle dynamics or simulations of tectonic and landscape processes. By and large these models are applied in a forward mode. Far more challenging is the inverse mode of operation. The difficulty arises from choices in methodology, computational limitations and from questions of uniqueness where model degrees of freedom exceed one billion. A growing community is beginning to address these challenges particularly in connection with sophisticated 3D forward modeling tools. Successful approaches to invert dynamic 3D computer simulations include adjoint techniques, Monte Carlo methods and automatic differentiation. Examples include the reconstruction of mantle and core flow over time, or the inversion of seismic wave fields. This session will survey significant progress in methods and application that has been made over recent years in the inversion of 3D computer models. It will bring together contributions from across the fields of tectonics, geodynamics and seismology. As is customary for AGU, we particularly welcome contributions from across disciplinary boundaries.

SM12: Towards a European Reference Model (Conveners: A. Morelli, J. Trampert)   Wien, Austria, 2006-04-02 08:00:00 - 2006-04-07 20:00:00

Reference Earth models are constantly used and leave a large imprint on many seismological activities ranging from earthquake location and source studies to structural inferences. The need for a specific, broadly accepted, seismological reference is particularly strong for Europe, where the uppermost mantle structure is very complex on a small lateral scale. There is, however, surprisingly little consensus of what a reference model is and should be able to provide. The very characteristics that define a 'good' reference model may be subject to debate, as they are related to specific applications. Making a seismic Earth model that is accepted by a large community, and is actually used in seismological practice, is therefore a long process, and involves a lot of people from a large group of disciplines. The aim of this session is to stimulate and continue this discussion within the broad European seismological community, and try and make an inventory of possible ingredients for a European reference Earth model. Any contributions from earthquake location, source studies and the analyses of body and surface waves in general, at various scales, which illustrate the importance, requirements, and uses of such a reference model are welcome. This session is sponsored by the SPICE Consortium, a Marie Curie Research Training Network and NERIES, an FP6 Integrated Infrastructure Initiative.

AGU special session: rotational seismology   San Francisco, 2006-12-11 00:00:00 - 2006-12-15 00:00:00

Seismology is based primarily on the observation and modelling of three-component translational ground motions. Nevertheless, theoretical seismologists (e.g., Aki and Richards, 1980, 2002) have argued for decades that the rotational part of ground motions should also be recorded. It is well known that standard seismometers are sensitive to rotations (just like tiltmeters are sensitive to translations). The lack of observations of rotational motions was mainly due to the limited resolution of rotation sensors. However, in the past few years ring lasers, fibre-optic gyros, and other measurement devices have led to the first significant and consistent observations of rotational motions suggesting that complete six-component measurements may be possible in the near future. Accurate measurements of rotational motions may have implications for (1) recovering the complete displacement history from seismometer recordings; (2) further constraining rupture properties; (3) extracting subsurface properties; and (4) providing additional information to earthquake engineers. The goal of this session is to discuss measurement devices, observations, modelling, theoretical aspects and potential applications of rotational ground motions. The session will be accompanied by the installation of an International Working Group on Rotational Seismology that aims at promoting investigations of all aspects of rotational motions in seismology and their implications for related fields such as earthquake engineering, geodesy, strong-motion seismology, tectonics, etc., and to share experience, data, software, and results in an open web-based environment.
