Twitter has today launched their Twitter Alerts service in the UK and Ireland after its testing period in the US was successful.

The service will allow participating emergency services to mark tweets sent via their official accounts as an alert, which will then be seen as critical information and sent to users as soon as possible, marked with an orange bell on the Twitter interface to stand out.

Alongside this, users can also sign up to receive notifications to their phones via an SMS or via a push notification on Android and iOS.

Currently participating organisations include the all of the UK’s police forcesAn Garda Síochána, the London Fire Brigade, the Mayor of London’s office, the Foreign Office, Ceop and the Environment Agency.

To sign up to the alerts you need to go to specific page for each of their Twitter accounts, the URL for which is twitter.com/[username]/alerts (replacing “[username]” for the services username).
