Kangra-Chamba-Dharamshala Belt: Seismic Risk and Preparedness
UPSC / SSC current affairs note
Why in news
In June 2026, the National Center for Seismology detected 16 earthquakes in the Kangra-Chamba area of Himachal Pradesh, highlighting the region's high seismic risk. The government informed Parliament about monitoring and mitigation measures, emphasizing the area's classification as Seismic Zone V.
Background
The Kangra-Chamba-Dharamshala belt lies in Seismic Zone V, the highest risk zone in India. Scientific studies indicate potential earthquakes of magnitude >7.0 due to tectonic activity. The region has a history of devastating earthquakes, including the 1905 Kangra earthquake.
Key facts
In June 2026, NCS detected 16 earthquakes in Kangra-Chamba area: 12 of magnitude 2.0-2.9, 3 of 3.0-3.9, 1 of 5.0-5.9, and none in 4.0-4.9 range.
Kangra-Chamba-Dharamshala belt falls in Seismic Zone V, the highest seismic risk zone in India.
Studies by NGRI and other institutes suggest earthquakes >7.0 magnitude are possible in this region.
NCS operates a national seismic network of 172 stations for 24x7 real-time monitoring; 7 stations are in Himachal Pradesh (Shimla, Dharamshala, Tissa, Sundernagar, Kalpa, Bhakra, Pong Dam).
NDMA conducts mock drills, training, disaster management plans, and strengthens emergency response systems.
Government promotes earthquake-resistant construction via National Building Code (NBC), BIS seismic design codes, and Model Building Bye-Laws; enforcement is by state governments and urban local bodies.
Seismic microzonation studies are carried out by scientific institutions and universities.
Government provides financial and technical assistance to all states, including Himachal Pradesh, under various disaster management and prevention schemes.
