On any given project, In Harm’s Way determines which areas are most at risk of tsunami disasters through a combination of compiling historical records and geological evidence of past earthquake and tsunami events. These data are used to construct seismic hazard and tsunami inundation maps that inform those in harm’s way what is likely to happen. Steps include:

  • Parameterize earthquakes and tsunamis from historical accounts to identify source regions and determine which areas are most exposed to earthquake and tsunami hazards.
  • Conduct geological and geophysical analysis of tsunami source regions and investigate the long-term slip history of active faults.
    Locate tsunami deposits to determine the extent of inundations of populated coastal regions from past tsunami events.
  • Construct numerical models of likely tsunami scenarios to estimate locations of source regions and magnitudes of past earthquake events, and to inform tsunami inundation risk analysis.
  • Construct tsunami inundation maps constrained by analysis of tsunami deposits and numerical modeling that predict which coastal areas are most at risk.
