India’s hazard pro le shows that about 59 percent area of India is vulnerable tomoderate to major earthquakes. It is evident from past earthquakes such as Manipur (2016), Nepal (2015), Sikkim (2011), Kashmir (2005), Bhuj (2001), Chamoli (1999), Jabalpur (1997) and Latur (1993) that all type of buildings sustain damage if not designedproperly. The experiences of these earthquakes have demonstrated that many typicalbuildings of different types have sustained signi cant damage in these earthquakes. More than 90% of the casualties in past earthquakes in India have occurred due to collapse of houses and structures. The loss of life and property can be minimized signi cantlyby ensuring better code compliance of upcoming constructions and undertaking seismicretro tting of existing buildings thereby making them earthquake resilient. Therefore, the need was felt to quantify the earthquake risk to the buildings so that decision makers putthe adequate structural measures after prioritizing the buildings.
NDMA through International Institute of Information Technology (IIIT) Hyderabadhas developed Earthquake Disaster Risk Index (EDRI) for 50 cities and 1 district on pilot basis. In this pilot study, the cities were selected based on the population density, housing threat factor and cities identi ed by Government of India as Smart Cities. The major areaof focus is the seismically active regions in India, i.e., seismic zones IV and V. The EDRIreport has been prepared based on the eld visit of 25 cities and collection of secondary data from the remaining cities’ of cials.
The risk has been categorized as Low, Medium and High for easy understanding of the decision-makers and town planners. We hope that the report will be of help to concerned city of cials and act as a guide towards disaster risk mitigation and preparedness efforts.
