Proposed Project –“Toward a Methodology for Tsunami Risk Analysis”
  • Project Motivation(from NTHMP Strategic Plan 2009-2013)
    • • NTHMP Performance Metrics:“… support a research effort to develop U.S. tsunami risk assessment methodologies” to “… develop quantitative tsunami hazard analysis techniques including source determination and probability of occurrence” and “determine applicability of economic and loss estimation tools (e.g. HAZUS) by 2010”
    • • NTHMP Risk Definition:‘‘. . . the product of the probability of the occurrence of a tsunami (i.e., the ‘‘hazard’’) times the loss of property and life due to the tsunami”
  • Study Context
    • • Nation needs multiple approaches for tsunami risk analysis
    • (e.g., life safety, economic impacts, livelihood impacts, natural resources, infrastructure resilience, etc.)
    • • Project focuses on life safety aspects of risk (e.g., evacuation potential)
      • • First steps towards one tool in a national toolbox of tsunami risk analysis
      • • Begins research dialogue on needed tools and approaches in national toolbox

Proposed Project –“Toward a Methodology for Tsunami Risk Analysis”

  • Goal: Improve understanding and metrics of societal risk to tsunamis
  • Objectives:
    • • Integrate probabilistic hazard models, socioeconomic asset distributions, evacuation time models, and casualty loss models
    • • Examine life safety aspects of HAZUS tool (e.g., forces on people and buildings)

Study Components:

III. Socioeconomic and

Evacuation Metrics (Nate Wood, USGS)

  • Community Engagement
  • (George Crawford, SRC)

II. Tsunami Hazard Modeling
