  12. Time independent earthquake forecast for Italy based on instrumental and historic seismicity and paleoseismology. Jordan, et al., 2011; http://www.annalsofgeophysics.eu/index.php/annals/article/view/5350/5371 probabilistic seismic hazard map for Italy: ground acceleration with a 10% probability of exceedance in 50 years

  13. Lessons of L'Aquila for Operational Earthquake Forecasting Presented by Tom Jordan, Director of the Southern California Earthquake Center (SCEC) and the W.M. Keck Foundation Professor of Earth Sciences at USC http://www.seismosoc.org/italy/ OEF (10:20-11:50): -Continual updating of authoritative information about future occurrence of potentially damaging earthquakes -The officially sanctioned dissemination of this information to enhance earthquake preparedness in threatened communities Earthquake probabilities -Probabilities of large earthquakes (even in areas of high seismicity) are low <<1%/day -High gain-low probability situations (100-1000x)

  14. Lessons of L'Aquila for Operational Earthquake Forecasting • Presented by Tom Jordan, Director of the Southern California Earthquake Center (SCEC) and the W.M. Keck Foundation Professor of Earth Sciences at USC • http://www.seismosoc.org/italy/ • L’Aquila (12:40-14:20) • -probability of a false alarm > failure to predict (100x) • -seismic activity had increased probability of a large event by ~100x • -Scientists enticed into addressing a simple yes-no question (“will we be hit by a large earthquake?”) • -Reassuring statements widely interpreted to be an anti-alarm

  15. Lessons of L'Aquila for Operational Earthquake Forecasting • Presented by Tom Jordan, Director of the Southern California Earthquake Center (SCEC) and the W.M. Keck Foundation Professor of Earth Sciences at USC • http://www.seismosoc.org/italy/ • Recommendations (14:20-16:49) • -Separate role of scientific advisors (objective information about natural hazards) from that of civil decision makers (weigh benefits of protective actions with costs of false alarms, other political considerations) • -Use probabilistic rather than deterministic statements in characterizing short term changes in seismic hazards (e.g. meteorological community)

  17. statement regarding California’s Immunity from Liability for Earthquake Predictions 955.1. The science of earthquake prediction is developing rapidly and, although still largely in a research stage, such predictions are now being initiated and are certain to continue into the future… It is the intent of this legislation to ensure that such actions are taken in the public interest by government agencies acting in a responsible manner without fear of consequent financial liabilities. -from John Parrish, California State Geologist 

  18. statement regarding California’s Immunity from Liability for Earthquake Predictions The state and its agencies and employees shall not be liable for any injury resulting from the issuance or non-issuance of a warning pursuant to this subdivision or for any acts or omissions in fact gathering, evaluation, or other activities leading up to the issuance or non-issuance of a warning. -from John Parrish, California State Geologist
