Key facts

1. The Kangra-Chamba-Dharamshala region is located in Seismic Zone V, India's highest earthquake hazard zone.
2. Scientific studies suggest the region can generate earthquakes exceeding magnitude 7.0.
3. In June 2026, 16 earthquakes were detected in the Kangra-Chamba region.
4. Of these, 12 were in the 2.0-2.9 magnitude range, 3 were in the 3.0-3.9 range, and 1 was in the 5.0-5.9 range.
5. The National Center for Seismology (NCS) under the Ministry of Earth Sciences monitors earthquakes nationwide.
6. NCS operates a 24x7 Earthquake Monitoring Centre in Kangra.
7. The National Seismological Network comprises 172 seismic stations across India.
8. Seven seismic stations are located in Himachal Pradesh: Shimla, Dharamshala, Tissa, Sundernagar, Kalpa, Bhakra, and Pong Dam.

Prelims pointers

• India is divided into seismic zones based on hazard levels.
• Seismic Zone V is the highest hazard zone.
• The National Center for Seismology (NCS) is responsible for earthquake monitoring in India.
• The Ministry of Earth Sciences (MoES) oversees the NCS.
• Himachal Pradesh has multiple seismic monitoring stations.

Mains practice question

Discuss the seismic vulnerability of the Kangra-Chamba-Dharamshala region and evaluate the measures being undertaken by the government for earthquake risk mitigation and preparedness.

Static linkage

The news relates to India's seismic zoning, disaster management preparedness, and the role of scientific institutions like the National Center for Seismology (NCS) and National Geophysical Research Institute (NGRI) in monitoring and assessing geological hazards.

Significance

The high seismic activity and classification of the Kangra-Chamba-Dharamshala belt in Seismic Zone V highlight the critical need for robust disaster preparedness and mitigation strategies. Understanding the potential for large magnitude earthquakes is crucial for urban planning, infrastructure development, and public safety in the region. Continuous monitoring by NCS and the expansion of the seismological network are vital steps in early warning and response.
