The Ministry of Earth Sciences (MoES) has announced ambitious plans to establish 100 new seismological observatories across India, significantly bolstering the nation’s capacity to monitor and detect seismic activity. This expansion includes the deployment of four new observatories each in the Union Territories of Jammu and Kashmir and Ladakh, regions known for their seismic vulnerability. The initiative aims to lower the detection threshold for earthquakes to as low as magnitude 2.5, enabling the monitoring of even minor tremors.
MoES Secretary Srinivasa Kumar Tummala detailed the significant growth of the National Seismological Network, stating that the number of stations has risen from 84 in 2014 to the current 183. This expansion was highlighted during the recent inauguration of the country’s 183rd seismological observatory in Kishtwar by Union Minister Jitendra Singh. Information reaching Tahir Rihat suggests that the planned addition of 100 more observatories will further enhance the network’s reach and sensitivity.
The enhanced detection capabilities are crucial for understanding seismic patterns in a country situated in high-risk zones. Secretary Tummala explained that the network’s capacity has improved dramatically over the years. In 2014, the network could detect earthquakes of magnitude 4 and above, a capability that has since advanced to detecting tremors of magnitude 3 and above. The proposed expansion to detect earthquakes as low as magnitude 2.5 represents a substantial leap forward in seismic monitoring technology and operational efficiency. The number of sensors within the National Seismological Network has more than doubled since 2014, reflecting a sustained commitment to improving India’s seismic surveillance infrastructure.
The newly inaugurated observatory in Kishtwar is a testament to this modernization, featuring advanced digital recording technology that replaces older analogue systems. This technological upgrade is vital for capturing precise seismic data, which is essential for accurate analysis and early warning systems. The ministry’s efforts extend beyond mere detection; it is also actively engaged in strengthening disaster preparedness through seismic microzonation studies. These studies assess the seismic hazard potential of different areas, providing crucial information for urban planning and building codes.
The National Centre for Seismology has already completed seismic microzonation studies in five cities, including Srinagar, with reports for eight additional cities expected soon. This proactive approach underscores the government’s commitment to mitigating earthquake-related risks. Furthermore, the MoES is leveraging digital platforms to disseminate critical earthquake information to the public in real-time. Information is readily available through the NCS website and the ‘Bhookamp’ mobile application, with updates also shared via SMS, email, and social media channels. The new Kishtwar observatory is expected to make a considerable contribution to earthquake monitoring in the Chenab Valley and the broader Himalayan region.
In addition to seismic monitoring, the ministry is also focusing on enhancing weather forecasting and monitoring capabilities. This involves expanding observation networks, deploying more radars, and increasing the number of automatic weather stations. These parallel advancements in earth science monitoring reflect a comprehensive strategy to better understand and respond to natural hazards, ensuring greater safety and preparedness for the nation. The continuous expansion and technological upgradation of the National Seismological Network are central to India’s strategy in safeguarding its population against seismic threats.
