Designed to help friends and family check on their nearest and dearest during natural disasters, Facebook is introducing a new Safety Check feature for its mobile app.
The tool works by sending a push notification to devices that are near to an affected area. Locations are determined by looking at the places listed in profiles, previous locations from the Nearby Friends feature, and the city from which you’re connecting to the Internet.
All a Facebook user needs to do in the event of an emergency is hit an “I’m safe” button and a news notification will be generated automatically on the Timeline.
