Twitter in Christchurch

On 22/02/11 in Christchurch, New Zealand there was an 6.4 magnitude earthquake which caused mass of damage and devastation for the country of New Zealand and the families of victims trapped or killed. The social networking site Twitter has helped saved many trapped peoples lives.

You are most probably wondering how Twitter, a social networking site where people update ‘tweet’ about what they are doing or something special that has happened. Well people who where trapped in buildings, houses etc. managed to ‘tweet’ where they where and rescue teams managed to get to them and saved them.

Twitter is good in a crisis because everyone can see what you tweet so people can tell people, who tell people and eventually reaches someone that can do something about it and help you out. Unlike Facebook where not everyone can see your page if you have the right privacy settings on. So if in a crisis someone made a ‘status’ saying they need help on facebook only the persons friends could see it. So in a situation like this twitter is better and more likely to help save your life.
