57 accounts have signed up for the service, including the UK’s 47 police forces, the London Fire Brigade, the Mayor of London’s office, the Foreign Office and the Environment Agency.
Says Twitter of the news:
All of the organisations participating in today’s launch already use Twitter as a tool to communicate important information to their followers. The added functionality of Twitter Alerts will help them reach their followers with important and accurate information during emergencies, natural disasters or when other communications services aren’t accessible.
Commander David Martin, in charge of emergency planning for the Metropolitan Police Service, said: “Getting fast and accurate information to the public in a major incident or terrorist attack really could make a life-saving difference.
“Using social networking sites, including Twitter, gives us additional ways to talk directly to the public. Twitter Alerts means that our messages will stand out when it most matters.”
To receive alerts from a participating body:
1. Go directly to a participating organisation’s alerts page, which you’ll find at
2. Click on the ‘Activate Alerts’ button
