Vulnerability
HAZUS is a powerful risk assessment software for
analyzing potential losses from earthquake,
hurricane wind, flood, storm surge, tsunami.
Damage Functionality

Estimation of Losses (risks)
WHERE were community assets damaged?
Physical Vulnerability
WHAT could be the hospital and shelter needs and
WHERE?
Public Safety
WHAT is the cost of the event in s in building
and Business losses?
Economic Security
HOW long will it take to recover from the event?
System Functionality
WHERE do vulnerable populations need social
services?
Social Vulnerability

Loss visualization tools for Risk Decision makers
Please approve my development permit to build a
house
Compare loss alternatives
Permitting officers and land use planners develop
and use risk profiles to recommend safe
development
Please show me where to focus my emergency
response and social services
Visualize losses in Emergency Management tool
Emergency Managers And support staff Develop and
interpret Loss models to guide response
