The site's "safety check" feature is now automatically activated whenever there is an event. It sends out a notification to all people thought to be in the area – telling themselves to tell Facebook they are safe, so they can show the same information to all their friends.
The system has been criticised in the past for causing undue panic , by suggesting that people who haven't yet marked themselves safe might be in danger.
The same problem appears to have happened again – with Facebook's safety check only alerting people about "The Fire in London" and covering areas including Newham in East London, on the absolute other side of the city.
The site now also lets people reach out to offer help. A number of people from across London are offering food and shelter to people potentially caught up in the fire, in which a number of people have been killed.
