India has officially launched its indigenous cell broadcast emergency alert system, which was tested on millions of users across the country. The National Disaster Management Authority (NDMA) conducted a test on Saturday, sending out messages titled 'Extremely Severe Alert' to inform citizens of the new disaster alert system.
The alert, which stated,
"India, launches Cell Broadcast using indigenous technology, for instant disaster alerting service for its citizens. Alert citizens, safe nation. No action is required by the public upon receipt of this message. This is a test message. - Government of India." The initiative, developed through the Centre for Development of Telematics (C-DOT) under the auspices of the Department of Telecommunications, aims to enhance alertness during disasters.
This system integrates with the SACHET platform—
Integrated Alert System—which will deliver critical real-time information during natural catastrophes. The Cell Broadcast system can potentially override phone settings, ensuring emergency messages are unavoidable, unlike traditional SMS alerts.
With proper testing, authorities aim to send crucial notifications about natural disasters such as
earthquakes, tsunamis, and severe weather warnings while also addressing man-made crises including gas leaks. Currently operational across all 36 states and union territories of India, the system has previously dispatched over
134 billion SMS alerts in 19 languages under various emergency scenarios.
This significant upgrade in disaster alert systems ensures a safer environment for India as it faces inevitable natural and man-made challenges in the future.
