Measuring Earthquakes Logarithmic scales and human perception.

 Seismologists use two scales when classifying earthquakes. 2) Modified Mercalli Scale 1) Richter Scale.

How is an Earthquake’s Epicenter Located? Seismic wave behavior –P waves arrive first, then S waves, then L and R –Average speeds for all these waves is.

COMPONENTTECHNOLOGY PRODUCT 1.ASSESSMENT Historical Studies Historical Database Field Surveys Inundation Maps Numerical Simul Evacuation Maps Hazard Reduction Strategy: Assessment

Risk Assessment What is likelihood of occurrence? What is expected earthquake impact? What is expected tsunami impact along coast? Numerical modelling Numerical modelling Need detailed bathymetry, topography TIME models (Tsunami Inundation Modeling Exchange) Modeling Exchange) Runup & inundation maps Runup & inundation maps Evacuation maps Evacuation maps January 3, 2002 Mw7.1 Vanuatu earthquake and tsunami Tsunami record and Tsunami model based on data

Model Results: Scientific Products

Assessment - Multiple Hazards Map Seismic Intensity (Modified Mercalli Scale) Seismic Intensity (Modified Mercalli Scale) Tsunami Inundation potential Tsunami Inundation potential Liquefaction susceptibility Liquefaction susceptibility Landslide potential Landslide potential Eureka, California

USGS, E. Giest

Assessment and Mitigation: Empirical Evacuation Maps 1. Post-Tsunami Scientific Survey - Data Collected: Runup, Inundation, Geology, Structural Damage Runup, Inundation, Geology, Structural Damage Eyewitness observations: wave arrival, behavior Eyewitness observations: wave arrival, behavior 2. Satellite Imagery (before and after) 3. Synthesize => Tsunami Event Flooding Map

Assessment and Mitigation: Empirical Evacuation Maps 4. Assuming worst case scenario, Considering coastal topography and elevation, roads and other easily managed walking paths, strength and height of buildings … Construct Tsunami Evacuation Map Identify Tsunami Shelters Construct Tsunami Evacuation Routes

Evacuation Maps – Safe Routes Planning Elements Identify ALL Stakeholders Identify ALL Stakeholders Workshops with Local Residents Workshops with Local Residents Single Access Roads Single Access Roads Congregation areas Congregation areas “Local tsunami evacuation maps developed based on modeling, maps and local oral history”
