1 USGS Decision-Making Tools for Pre-Earthquake Mitigation and Post-Earthquake Response Tools of the Trade DAVID WALD United States Geological Survey NEHRP Workshop: Developing Earthquake Scenarios Sept 17-18, 18, 2008 San Francisco, CA USGS National Earthquake Information Center, Golden, Colorado USGS Earthquake Web Pages Earthquake Notification Service (ENS) Did You Feel It? CISN Display ShakeMap ShakeCast Prompt Assessment of Global Earthquakes for Response (PAGER) Overview Focus here primarily on hazard (shaking) side of the scenario, and related information tools. ShakeMap hand-off to ShakeCast or HAZUS-MH for losses & comprehensive impact assessment. These are situational awareness tools associated with real events thus, should be used for scenarios. Tools available range from passive (web pages) to active (notifications), simple to sophisticated (applications), easy-to-install to substantial IT investments.

2 Earthquake Notification Service (ENS) ENS Sign up to receive notifications by or cell/pda for any earthquake nationally (located by the regional networks of the ANSS) or nationally & globally (located by the NEIC). Click to edit Master title style Customize your notifications based on geographic boundaries, magnitude threshold & time of day. Click to edit Master subtitle style Multiple user profiles - get for smaller earthquakes but get text messages for the big ones! Earthquake Notification Service usgs.gov/ens/ M5.4 Alum Rock, CA Earthquake, Oct. 30, 2007 Did You Feel It? Macroseismic data collection via the Internet ShakeMap Automatic shaking intensity maps from Seismic data Acceleration (%g) ShakeMap Did You Feel It? 64,000 responses; Max Rate 48/sec(!) (sustained rate of 22/sec for 30 min) M5.2 Illinois Earthquake, April 18, 2008 Did You Feel It? 38K/30 min

3 ShakeMap Did You Feel It? Over 1 Million Individual Responses Nationally! (9 Years of DYFI? Data) Did You Feel it? DYFI? Intensity Map as a part of situational awareness Constraints for ShakeMap (areas of low instrumentation, domestically & internationally) Input into FEMA s HAZUS-MH, PAGER Would be easy to mimic DYFI page for a scenario? REPLACE WITH UPDATE ShakeMap Home Page ShakeMap Scenarios: Pacific Northwest ShakeMap Scenarios: Alaska

Other ShakeCast Uses: Global Cities ROVER: Rapid Observation of Vulnerability and Estimation of Risk Implements FEMA 154 on smart phone Rapidly create an inventory buildings exposed to risk; ID those warranting detailed examination Integrated with HAZUS & ShakeCast Based on slides from K. Porter

10 Future for Scenarios? Notifications from ENS/CISN Display. ShakeMap for standardized products o Need more comprehensive Archive of ShakeMap Scenarios o Need search by location, name, magnitude, etc. ShakeMap hand-off to ShakeCast, HAZUS-MH, etc., for losses & comprehensive impact assessment. ShakeCast/Rover for exercises & utility/structure impact assessment. PAGER for very rapid, overall impact assessment; HAZUS-MH for detailed losses, needs, & maps.
