Facebook has launched a new feature called Safety Check that allows users to inform their friends and family about their safety in the event of a disaster or crisis using a check-in system.

To determine your location, Facebook looks at the city listed on your profile and recognizes the city where internet services are being used. The company will also use data from the Nearby Friends feature if a user has turned it on. Safety Check's sign-in feature is similar in nature to the Safe and Well website created by the American Red Cross which also allows individuals to register themselves as safe and inform their loved ones of their current conditions.
Facebook's new Safety Check feature comes after the company launched an update to its iOS app yesterday that added support for the iPhone 6 and the iPhone 6 Plus. Facebook for iOS is a free app and can be downloaded from the App Store. [Direct Link]
