Strengthening emergency messaging
Disaster Communication Systems in India: The Department of Telecommunications (DoT) and the National Disaster Management Authority (NDMA) are upgrading India’s disaster communication systems. The goal is to deliver timely and location-specific alerts to people during emergencies such as cyclones, earthquakes, and floods.
SACHET system for SMS alerts
A key innovation is the Integrated Alert System (SACHET). It uses the Common Alerting Protocol (CAP) as recommended by the International Telecommunication Union (ITU). This system is active in all 36 States and Union Territories.
SACHET sends alerts via SMS to specific geographic regions. It supports over 19 languages, ensuring local-level communication. Since its launch, more than 6,899 crore alerts have been sent for natural disasters, cyclonic disturbances, and weather events.
Static GK fact: The Common Alerting Protocol (CAP) is a globally accepted format for sharing emergency messages.
Introducing Cell Broadcast technology
To expand its alert capabilities, the DoT is also deploying Cell Broadcast (CB) technology. Unlike SMS, CB sends real-time alerts to all phones in an affected area, regardless of network provider. This is vital during events like tsunamis or major tremors.
The Centre for Development of Telematics (C-DOT) is leading the development of the CB system. This system will deliver multilingual alerts in real-time, increasing public preparedness and safety.
Static GK fact: Cell Broadcast messages do not clog the mobile network and can reach millions instantly.
Testing underway for CB system
A 2–4 week testing phase has started to check system efficiency. Mobile phones with CB test channels will receive alerts in English and Hindi multiple times during this phase. These messages are for testing only, and no public action is needed.
This phase ensures that the CB system works effectively across all telecom networks, including remote regions and dense urban zones.
Citizens’ cooperation matters
Public cooperation is crucial. The DoT has requested citizens to ignore test messages and not panic. These tests validate the infrastructure and prepare the nation for smooth functioning of the system during real emergencies.
Once launched fully, the system will send alerts in multiple Indian languages, ensuring no citizen is left uninformed.
A step towards national resilience
This integrated communication effort marks a transformational step in India’s disaster management approach. With timely alerts and area-specific messaging, the country moves towards a more resilient and prepared future.
Static GK Tip: The Disaster Management Act, 2005 is the legislative foundation for India’s disaster response framework.
