Communications system used to communicate with the publicReverse 9-1-1 is a public safety communications technology used by public safety organizations in Canada and the United States to communicate with groups of people in a defined geographic area. The system uses a database of telephone numbers and associated addresses, which, when tied into geographic information systems (GIS), can be used to deliver recorded emergency notifications to a selected set of telephone service subscribers.
Background
Reverse 9-1-1 was developed by Sigma Micro Corporation, later known as Sigma Communications, in 1993. After a number of corporate acquisitions, Motorola Solutions ultimately gained ownership of the technology and rights developed by Sigma, and Motorola has folded Reverse 9-1-1 into their Vesta suite of public safety systems.
Case studies
The system is used to notify residents in emergency situations, for example:
- During the 2010 Boston water emergency, government agencies used the system to notify a large number of Boston-area residents in particular neighborhoods to boil water before drinking.
- During the much more contained 2004 bulldozer rampage in Granby, Colorado, authorities used Reverse 911 to notify the approximately 1,500 residents of the town to evacuate from the bulldozer's path.
- During the 2011 Tōhoku earthquake and tsunami, Seaside and Astoria, Oregon, residents were notified by Reverse 911 and sirens to evacuate low-lying areas.
- When the improvised explosive devices in the Aurora, Colorado, apartment of mass murderer James Holmes were detonated by police, Reverse 911 was used to notify nearby residents of the evacuation order.
- On December 14, 2012, Reverse 911 was used to notify parents in the Sandy Hook community of Newtown, Connecticut, of the mass shooting there.
- During the manhunt for suspects involved in the Boston Marathon bombing, Reverse 911 was used to notify residents of Watertown, Massachusetts, to remain in their homes.
- In October 2014, some Dallas, Texas, residents were notified of the city's second Ebola infection case by a Reverse 911 call.
- In 2023, residents of South Coventry Township, PA received late-night reverse 911 calls to lock their doors and stay inside during the search for escaped murderer Danilo Cavalcante.
