Abstract: The U.S. Geological Survey (USGS) has developed several near-real time earthquake information systems that provide rapid and automated alerting of estimated economic and human impacts following earthquakes. In this talk I describe the four components that rapidly assess an earthquake’s impact. First, earthquakes trigger rapid source characterization; second, these source parameters help inform our estimates of shaking-distribution (ShakeMap). Third, losses are modeled by computing populations exposed per shaking intensity level, and country-specific loss functions are used to provide estimates of economic impact and potential casualties (PAGER). Finally, these uncertain loss estimates are communicated in an appropriate form for actionable decision-making among a variety of users.
Biography: Dr. Wald is a Seismologist with the USGS in Golden, CO and is on the Geophysics Faculty at the School of Mines. He earned his Ph.D. in Geophysics from Caltech in 1993. Dr. Wald is involved in research, development and operations of several real-time information systems at the USGS National Earthquake Information Center. He developed and manages “ShakeMap”, “Did You Feel it?”, and is responsible for developing other systems for post-earthquake response and pre-earthquake mitigation, including ShakeCast and PAGER.
Dr. Wald’s scientific interests include the estimation of rupture process from modern and historic earthquakes using source inversion, earthquake source physics, analysis of ground motion hazards, and earthquake loss modeling. Dr. Wald is an Associate Editor for EERI’s Earthquake Spectra, serves on both EERI’s and SSA’s Board of Directors served as the IRIS/SSA’s Distinguished Lecturer in 2004 and is currently the 2014 EERI Distinguished Lecturer. Dr. Wald was awarded SSA’s Frank Press Public Service Award in 2009.
