Twitter has launched a new broadcast system that will allow users to receive important information and updates from creditable organisations during emergencies and national disasters.
Called Twitter Alerts, the opt-in service already has the support of a number of public institutions and non-governmental organisations (NGOs) in the U.S., Japan and Korea, with plans to expand the platform to other countries soon.
Here’s the scoop from the official Twitter blog:
If you sign up to receive an account’s Twitter Alerts, you will receive a notification directly to your phone whenever that account marks a Tweet as an alert. Notifications are delivered via SMS, and if you use Twitter for iPhone or Twitter for Android, you’ll also receive a push notification*. Alerts also appear differently on your home timeline from regular Tweets; they will be indicated with an orange bell.
Here’s how it works:
1. Go directly to a participating organisation’s alerts page, which you’ll find at
2. Click on the ‘Activate Alerts’ button
As an example of what to expect, here’s FEMA‘s page:
