Subject: text for scenario 3; CV attached Resent-Date: Sat, 18 Dec 1999 16:55:13 -0500 Resent-From: Geoffrey Fox Resent-To: p_gcf@npac.syr.edu Date: Sat, 18 Dec 1999 12:07:51 -0800 From: Lisa Grant To: gcf@npac.syr.edu CC: turcotte@geology.geo.cornell.edu, klein@buphyc.bu.edu Dear Geoffrey, Below is the proposed text for the scenario 3 portion of the preproposal. It was hand drafted by Bill Klein and Don Turcotte and given to me for transcription and editing. My additions to their original text are enclosed in [brackets]. I have also attached a short (approx. 2 pg. version of my CV) as requested. I will be checking my email most days during the holidays if you need anything further. I would appreciate receiving a draft of the full text when it is available. Thank you and Happy Holidays! Lisa Grant ________________________________________________________________ Draft of Scenario 3 - "Linkage of fundamental theoretical investigations with observations and simulations; complex systems and data understanding" by Klein, Turcotte and Grant The primary goal of the theoretical research is to develop a comprehensive global earthquake model and to provide a theoretical framework through which the data generated by simulating this model can be understood. We expect that this model will cover time scales from seconds, the time associated with a rupture, to centuries, the scale of strain accumulation [and release]. In addition, this model will contain most of the aspects of real faults; characteristics of wave propagation, frictional behavior and fault interaction will be included for example. In order to develop such a model we need to understand what the essential features of fault systems are and how omission of these features affects the physics obtained from the model. As a first step we are proposing to investigate a wide range of models to ascertain what features of the physics are robust and what aspects rely on model detail. These models range from cellular automaton versions of single faults to slider block and elastodynamic models with various friction forces to stochastic models of fault systems. Each model provides insight into different, but overlapping aspects of fault dynamics. To implement this investigation will require the ability to simulate these models on time and size scales presently unattainable, and to compare data sets from different models with each other and [with] observations of real faults. To accomplish these goals we propose to develop and refine both efficient algorithms such as fast multipole methods and to explore acceleration techniques. We will also utilize and develop web based interactions to facilitate comparisons of models and to validate models by comparison with real data. [For initial efforts we propose to develop a standard set of real data for calibration of models or comparison with results of simulations. By using the same real data set for all models and simulations we facilitate comparison of model effectiveness and establish real (rather than theoretical) performance standards for simulation results. The Southern California Earthquake Center Data Center and affiliated data repositories provide a wealth of southern California earthquake data types and fault geology information. We propose to format and organize these data sets for use with our models.] Name: LGrantGEMCV.doc LGrantGEMCV.doc Type: Winword File (application/msword) Encoding: base64 --------------------------------------------------------------------- _______________________________________________ Prof. Lisa B.
