Indian Sub-Continent is Amongst the Most Earthquake Prone Areas in the World
Dec 28, 2015

The Indian sub-continent is amongst the most earthquake prone areas in the world. ESSO-National Center for Seismology (NCS) is monitoring earthquake activity in and around the county round the clock through its national seismological network along with other global/regional seismicity monitoring networks.

  • Earthquakes occur along the Alpine-Himalayan belt, which also runs through the Andaman Sumatra arc, Indo-Burmese arc, and Himalayan arc. 

  • The continued collision/subduction of Indian plate with the Eurasian and Sunda plates cause these earthquakes. 

  • A few earthquakes also occur within the peninsular shield region of India, which are grouped under intra-plate category and occur due to internal deformation of the plate. 

The Earth System Science Organization (ESSO) -India Meteorological Department (IMD) is responsible for monitoring, detection and forecasting of weather and climate extremes including severe weather events such as cyclones, heavy rainfall, extreme temperature etc. Such forecasts are issued at national, regional and state levels. In order to provide early warning of severe weather events, ESSO-IMD has setup a network of state meteorological centres to have better coordination with a state and district level agencies.

The Indian Tsunami Early Warning Centre (ITEWC) has all necessary infrastructure and capabilities to give tsunami advisories to India as well as to Indian Ocean countries. ITEWS has been designated as one of the Regional Tsunami Service Providers for the entire Indian Ocean Region by the Intergovernmental Oceanographic Commission (IOC) of UNESCO on 12 October 2011. Since then, ITEWC is providing tsunami warnings and related services to all countries in the Indian Ocean Rim (24 Countries) beyond fully serving the India’s coastline/Islands.

The centre is capable of detecting tsunamigenic earthquakes occurring in the Indian Ocean as well as in the Global Oceans within 10 minutes of their occurrence and disseminates the advisories to the concerned authorities within 20 minutes through email, fax, SMS, GTS and website.

Bureau of Indian Standards (BIS) has published several guidelines and building codes for construction of earthquake resistant structures and for retrofitting of existing buildings. These guidelines are in wide circulation amongst the public and the administrative authorities responsible for the design and construction of earthquake resistant structures in earthquake prone areas.

National Disaster Management Authority (NDMA), Ministry of Home Affairs (MHA), Ministry of Earth Sciences and other state Disaster Management Authorities, have also taken up various initiatives to educate and enhance awareness amongst general public and school children on the general aspects of earthquakes, their impacts and measures to mitigate losses caused by them. A National Disaster Response Force (NDRF) is also functional under the general superintendence, direction and control of the NDMA for the purpose of specialized response to natural and man-made disasters.

Markets, schools, hospitals and Railway and Bus stations, airports etc. are regularly sensitized by organizing mock drills and information dissemination relating to evacuation and steps to be taken during rescue and relief operations. 

In addition satellite based, Cyclone Warning Dissemination System (CWDS) comprising 222 CWDSs have been installed in Andhra Pradesh (134), Odisha (44), Tamilnadu (42) and Pondicherry (02).
