Explain the details of Tsunami Warning System of India.

Question

Ghissu Editorial · Accepted Answer

India's Tsunami Warning System, built after the 2004 tsunami and run by INCOIS Hyderabad under the Ministry of Earth Sciences, uses seismic stations, Bottom Pressure Recorders and tide gauges to detect undersea quakes. It can issue a first advisory within about 10 minutes, relayed via MHA and state emergency centres.

**Introduction**

The 2004 Indian Ocean tsunami exposed India’s need for a robust tsunami warning system to protect its extensive coastline, including ==Andhra Pradesh’s 974 km coast==, prompting the establishment of a dedicated early warning mechanism.

**Components and Functioning**

1. **Integrated Monitoring Network**: India’s system combines seismic stations and Bottom Pressure Recorders (BPRs), with ==four BPRs in the Bay of Bengal== and two in the Arabian Sea, enabling rapid detection of seismic events and sea-level anomalies.

2. **Data Transmission and Alert Generation**: Seismic data reaches INCOIS in real time, which can issue the first tsunami advisory within about 10 minutes using satellite communication, including Iridium transceivers.

**Technological and Institutional Framework**

1. **Advanced Infrastructure**: INCOIS employs sophisticated sensors and computational models to analyze seismic data and predict tsunami wave propagation, supported by the Ministry of Earth Sciences.

2. **Institutional Coordination**: INCOIS coordinates with the Indian Meteorological Department and international oceanographic bodies; state-level centers like ==Andhra Pradesh’s State Emergency Operations Centre== implement localized responses per NDMA’s Tsunami Risk Management Guidelines.

**Role of Key Agencies and Effectiveness**

2. **State and Central Response**: The Ministry of Home Affairs and state governments disseminate warnings and coordinate evacuations; ==Andhra Pradesh integrates tsunami alerts into coastal disaster plans==.

3. **Operational Success and Challenges**: The system successfully detected the 2007 Indonesia tsunami threat, though audits reveal gaps in buoy coverage and funding, requiring upgrades.

**Way Forward**

1. **Network Expansion**: Plans include increasing active BPRs and automated observatories, especially along ==Andhra Pradesh’s vulnerable coast==, to improve real-time⟦1⟧ accuracy.

**Conclusion**

India’s Tsunami Warning System, through technological innovation and institutional synergy, has strengthened coastal disaster preparedness and reduced tsunami risks.
