3rd International ACES Meeting Maui, Hawaii May 6-10, 2002 Sponsored by NASA and NSF SESWG Living on a Restless Planet Solid Earth Science Working Group Report NASA Headquarters 3 April 2002 SESWG The SESWG Charter • To guide the science community in the development of a recommended long-term vision and strategy for solid-Earth science at NASA Chair: Sean C. Solomon Victor R. Baker Jeremy Bloxham Douglas Burbank Ben Chao Alan Chave Andrea Donnellan Alan Gillespie Thomas A. Herring Raymond Jeanloz Bernard Minster Walter C. Pitman, III Eric Rignot Mark Simons Byron Tapley Donald Turcotte Mary Lou C. Zoback John LaBrecque (ex-officio) Charles Elachi (ex-officio) Diane Evans (ex-officio) Web Page: http://solidearth.jpl.nasa.gov http://gaia.hq.nasa.gov/seswg/index.cfm E-mail: [email protected] SESWG Six Key Questions 1. 2. 3. What is the nature of deformation at plate boundaries and what are the implications for earthquake hazards? 4. How do magmatic systems evolve and under what conditions do volcanoes erupt? 5. What are the dynamics of the mantle and crust and how does the Earth’s surface respond? 6. What are the dynamics of the Earth’s magnetic field and its interactions with the Earth system? How do tectonics and climate interact to shape the Earth’s surface and create natural hazards? What are the interactions among ice masses, oceans, and the solid Earth and their implications for sea level change? http://solidearth.jpl.nasa.gov Earth Science Enterprise Computational Technology Workshop April 30 – May 2, 2002 Chairs: Andrea Donnellan, JPL John Ries (UT/CSR) John Rundle (U.
