Twitter has announced a new system that enables public institutions and other organisations to send emergency alerts via text message and push notifications during times of crisis.
Users can sign up to receive Twitter Alerts from specific accounts and then notifications are sent directly to their phones whenever an account marks a tweet as an alert.
The emergency alerts will feature an orange bell on users' home timelines to identify them from normal messages.
Twitter already has more than 70 organisations and bodies signed up to the new system, including the US Federal Emergency Management Agency (FEMA), the World Health Organisation and the New Jersey State Police
To sign up to alerts from a particular Twitter account, visit their set up page at twitter.com/[insert username]/alerts.
What Twitter Alerts will be used for:
- Warnings for imminent dangers
- Preventive instructions
- Evacuation directions
- Urgent safety alerts
- Information on access to essential resources
- Information on critical transit and utility outages
- Crowd and misinformation management
