Safety of Vital Installations against Earthquake and Tsunami and Landslides


1. Context/Background

It is pertinent to note that a very ambitious initiative has been taken by the Government to enhance the basic infrastructure which includes: Smart cities; Industrial corridors; new Power plants etc. These structures need to be functional over a long period of time. 

Natural disasters such as landslides, earthquake, cyclone, flood, and tsunami cause catastrophic damages not only in the physical form but also, in the social and economic context.  Disaster mitigation involves a broad range of scientific interventions before, during and after a natural disaster to prevent or minimise the loss of life and property. There are two types of disasters: one natural and another man-made. Natural calamities include: Earthquakes; Cyclones; Tsunamis; Floods; and Landslides, whereas man-made usually includes terrorist-threats; poor status of built-in structures particularly vital installations such as Power-grid infrastructure; Power Plants (Hydroelectric, Thermal, Gas and Nuclear); Water supply systems (Overhead and underground tanks, distribution systems); Roads, Railway bridges, Hospitals and others.

2. Problems to be addressed

Following issues are envisaged to be addressed through two Work Packages titled ‘Safety of Vital Installations through Earthquake Hazard Assessment studies’ and ‘Safety of Vital Installations against Landslides’:

  • Earthquake Hazard quantification studies in Uttarakhand
  • Locating spatial distribution of inland inundation, including generation and propagation of tsunami for protection and mitigation planning in coastal regions
  • Tsunami Forces on a few identified structures along the east coast of India.

3. Aims and objectives

The primary objectives are to assess the Risk involved due to seismic hazard for the life line structures mentioned below. Thestudy shall dwell upon the prevalent seismic hazard and shall be used for assessing the safety of critical installations and lifeline structures in Uttarakhandwith special emphasis on      

  • Bridges both road bridges and railways especially the older ones;
  • Elevated Water Tanks;
  • Hospitals and Schools
  • Critical installations
