How useful is the Facebook 'Safety Check' function during terrorism and disaster? A closer look in my CFI blog... When the attacks in London happened, many people used Facebook's "Safety Check" functions to alert friends and family that they were safe. When launching the feature, Facebook CEO Mark Zuckerberg announced, "When disasters happen, people need to know their loved ones are safe. It's moments like this that being able to connect really matters." As Wired explains, "When activated, Safety Check locates Facebook users near a disaster site through the city they list on their profile, or from where they last used the Internet. Users then receive a notification asking to confirm that they're safe or to say that they weren't in the affected area. Those who choose ‘safe' generate a notification to their friends and followers, who can track how many of their friends were affected." I'm sure the effort is well intended, but my natural skepticism led me to wonder just how useful it really is. There are about 10 million people in London at any given time (8.5 million residents plus another 1.5 million visitors per month, roughly) and the chances that any given one of them will be harmed or killed in terrorism or a natural disaster is very remote.
