Browse by topicEvent Brief provides automated, near-real-time hazard impact assessments for hazards impacting (or predicted to impact) population. An Event Brief will be made available (triggered) when DisasterAWARE detects that population fall within the areas listed for each hazard below.
Note: Event brief provides enhanced and expanded exposure and impact information to help you quickly answer What happened? When and where did it happen? How bad is it? However, if a hazard does not meet the trigger requirements listed below to issue an Event Brief, preliminary exposure estimates can be accessed by selecting the “More Information” button under that hazard’s Information tab. Be sure to revisit the hazard to see if an Event Brief has been created and for updates.
