QuakeSim's earthquake forecasting methodology scored well in a recent competition organized by the Southern California Earthquake Center. In 2005 seven forecasts were submitted to the competition. The QuakeSim forecast, led by Professor John Rundle at UC Davis was most accurate in picking the locations of future earthquakes. Results were published in the September 26, 2011 issue of the Proceedings of the National Academy of Sciences.

QuakeSim Participation at the Southern California Earthquake Center Annual Meeting

QuakeSim team members presented ten posters at the Southern California Earthquake Center Annual Meeting in Palm Springs on topics ranging from the El Mayor-Cucupah earthquake, transient detection, paleoseismic results, and earthquake simulators. Donnellan presented at talk on UAVSAR data, modeling, and results at the workshop on the El Mayor-Cucapah Science and Earthquake Response. Granat and Parker participated in the workshop on Automating the Transient Detection Process under Yehuda Bock's AIST project, which is led by Sharon Kedar at JPL. They used time series analysis methods developed under QuakeSim leveraging off of years of previously funded QuakeSim work. The group successfully identified the transient signal. Granat and Parker have managed to detect all the transient signals in the phases they have participated in, with no false alarms.

Andrea Donnellan talks about studying earthquakes around the world and NASA technology for earthquakes at JPL's Internal Earth Day Event. This 12 minute talk is one in a series of talks and starts at 1:07 in the recording.
Minor corrections: The GPS station referred to in Antarctica is uplifting at 12 mm/yr (not 12 cm/yr) and the Chilean earthquake referred to occurred in 1960 (not 1964).

Fault finding: UCI seismologist finds far more frequent earthquakes along the San Andreas
Sun, 03/06/2011 - 14:37
(PhysOrg.com) -- UCI seismologist Lisa Grant Ludwig finds far more frequent earthquakes along the San Andreas fault. Findings in the Sept. 1 issue of Geology conclude that for the last 700 years, earthquakes have occurred far more often than once thought in the Carrizo Plain section, as often as every 45 to 144 years. The last big quake there was in 1857, more than 150 years ago.
