SCEC’s “M8” earthquake simulation breaks computational records, promises faster and more detailed models of future earthquakes
Nov. 18 -- A multi-disciplinary team of researchers presented the world’s most advanced earthquake shaking simulation at the Supercomputing 2010 (SC10) conference this week in New Orleans. The research was selected as a finalist for the Gordon Bell Prize, awarded at the annual conference for outstanding achievement in high-performance computing applications. The “M8” simulation models how the ground will shake in a magnitude 8.0 earthquake on the southern San Andreas Fault. The simulation covers a larger area, in greater detail, than previously possible. Perhaps most importantly, the development of the M8 simulation advances the state-of-the-art in terms of the speed and efficiency at which such calculations can be performed.
The Southern California Earthquake Center (SCEC) is a community of over 600 scientists, students, and others at more than 60 institutions worldwide, headquartered at the University of Southern California. SCEC is funded by the National Science Foundation and the U.S. Geological Survey to develop a comprehensive understanding of earthquakes in Southern California and elsewhere, and to communicate knowledge for reducing earthquake risk. SDSU is one of several core institutions involved with SCEC.
