Dr Jitendra Singh, Union Minister of State (Independent Charge) for Earth Sciences, inaugurated India's 183rd seismological observatory at Kishtwar, Jammu & Kashmir, on 2 Nov 2026. It is the fourth in J&K – the others are at Jammu, Srinagar and Udhampur. Fitted with modern digital seismic equipment, it will send real-time data to the 24x7 earthquake monitoring centre of the National Center for Seismology (NCS) in New Delhi, strengthening earthquake monitoring and disaster preparedness in the Himalaya. Officials said Kishtwar 'sits in the middle of a fault line'.

Background

• Body: the National Center for Seismology (NCS) is the Government of India's nodal agency for monitoring earthquake activity; it was set up in Aug 2014 under the Ministry of Earth Sciences. Its work includes 24x7 monitoring, a seismological data centre and city seismic microzonation studies.
• History: after the 1897 Shillong plateau earthquake, India's first seismological observatory was set up at Alipore, Calcutta, on 1 Dec 1898. The national network grew to 6 stations in 1940, 15 in 1960 and 18 in 1970.
• Seismic zones: the Bureau of Indian Standards (BIS) code IS 1893 divides India into four zones, II to V (V = highest risk). IS 1893:2025, issued in Nov 2025, added a new 'Zone VI' covering the whole Himalaya and the Andaman & Nicobar Islands, but BIS withdrew it in March 2026 – the 2016 standard is back in force.
• Science: the point underground where a quake starts is the 'focus' (hypocentre); the point on the surface directly above it is the 'epicentre'. The Richter scale, devised by Charles Richter in 1935, is a logarithmic scale of an earthquake's 'magnitude' (energy released); the 'intensity' of shaking and damage is measured on the Mercalli scale. A seismograph records seismic waves.

Tamil Nadu link: according to the Ministry of Earth Sciences' Lok Sabha reply (20 Mar 2020), Tamil Nadu lies in seismic Zones II and III. Chennai, Tiruvallur, Vellore, Chengalpattu, Ranipet, Kanniyakumari, Tirupattur and Tiruppur are in Zone III; Tiruchirappalli, Madurai, Thanjavur, Nagapattinam, Ramanathapuram, Thoothukudi and others in Zone II; Coimbatore, Salem, the Nilgiris, Kancheepuram and some others straddle both.
