Life is uncertain… • Disasters? • Climate Change? • The weather tomorrow? We need tools that enable informed decision-making about these complex, dynamic systems

Disaster Impact Analysis - Scenario or Stochastic - Probabilistic Risk Modeling Vulnerability (of house to wind) Risk (i.e probable loss) Hazard (i.e. hurricane wind) Exposure (i.e. houses)
CAPRA ~ Central American Probabilistic Risk Assessment CAPRA is an ongoing initiative to develop and enhance a set of free and open source GIS-based tools to understand, communicate and support decisions to reduce disaster risk within in Central America.

Stochastic Hazard Modeling Stochastic Event Set = All events that could impact a region Frequency : How likely is this event? Annual probability of occurrence (i.e. 1/ 100) Severity : How strong is the event? Hurricane Cat 5 What does the event look like? Track, Point of landfall, wind field, etc
