This report was released by Fairfax’s Office of Public Affairs, which, in keeping with the County’s Emergency Operations Plan, coordinates and disseminates all information related to major incidents.

The report details how users interacted with information on the Fairfax Emergency Information Blog, Facebook page, Twitter account, mobile app, and other online platforms.

Key findings included the following:

  • Fairfax launched an emergency information blog during the hurricane which received over 50,000 views (more than any other county web page during the same time period).
  • Fairfax County’s Facebook page received 335,000 post views and was the primary way people received information from the county on Hurricane Irene.
  • The county’s website saw a 3,000% increase in the number of views to select emergency web pages during the preparation, response, and recovery for Hurricane Irene.
  • There were 289 downloads of the county’s iPhone app during the preparation, response, and recovery for Hurricane Irene (up from 75 during a similar time period).

The full report is available here.
