From Notes on GEM Meeting March 99 GEM Group Meeting Boulder Colorado -- March 13-14 1999. by Geoffrey C. Fox


1 Klein: Role of Simple Models? Do these first?
  • Use this to test importance of friction laws etc.
  • look at hierarchy of overlapping models: slider, CA, full featured continuum simulation
  • robust features in simple models can either be wrong or irrelevant!
  • To get believable results, one must have multiple efforts
2 Whitcomb: Climate community has a multiscale activity where simulations at several scales are linked via boundary conditions
3 Before large scale simulations, need to clarify disagreements in basic simulations ?
4 Sammis: science is critical
  • science is simple and elegant
  • makes predictions
  • can be falsified
5 Large catalog of observations in need of modeling
  • data patterns (in seismicity) suggest there is something to predict
6 Lisa Grant, Kerry Sieh on integrating data with GEM
  • larger earthquakes are most important societally
  • data + models,GEMCI gives validated predictions
7 Many gaps in data space needed for GEM -- 10 year proposal from Kerry
8 They need good database technology (GEMXML)
