Abstract
History of earthquakes in our country demonstrate vulnerability to seismic hazards. The recent past, devastating earthquakes in urban areas in India causing heavy economical losses in terms of loss of life, property, disruption of services and damage to environment have been of great concern; the experiences have prompted to carry out in-depth studies and come out with solutions and policies which will go a long way in minimizing the damages caused by seismic ground motions. In this context, microzonation of urban areas have assumed new dimensions. Delhi, the capital city of India has a long seismic history and is being affected by local as well as by the Himalayan earthquakes. The Jabalpur urban agglomeration lies in the field of recurrent seismicity ascribed to the reverse activation of Son-Narmada South Fault. Dehradun, the capital city of Uttaranchal is located in the foot hills of Himalayas and is sitting on a tectonically isolated block confined between main boundary thrust & Himalayan Frontal Thrust. Macroseismic surveys of the earthquake effects have unraveled site-dependent ground amplifications increasing the vulnerability of the built environment to seismic hazards. Hence, a need is felt to carry out prognostic damage scenario of existing building stocks in urban area, review the existing codal provision of buildings so that appropriate disaster mitigation measures can be evolved. Keeping this in view, CBRI, Roorkee (India) has carried out studies to generate inputs on vulnerability of engineered and non-engineered structures and anthropic parameters of population living in dwelling susceptible to damage and other exposure factors for fourth level seismic risk microzonation with engineering seismological perspective. The paper briefly describes the microzonation studies initiated in India for Delhi, the capital city of India, Jabalpur & Dehradun, the capital of newly formed Indian state, Uttaranchal. The paper presents two approaches namely Demand Capacity Ratio (DCR) approach & Rapid Screening Procedure(RSP) for assessment of seismic vulnerability of existing building stocks.

Microzonation Studies for Delhi, Jabalpur & Dehradun as Impacted by Bhuj Earthquake

History of earthquakes in our country demonstrate vulnerability to seismic hazards. The recent past, devastating earthquakes in urban areas in India causing heavy economical losses in terms of loss of life, property, disruption of services and damage to environment have been of great concern; the experiences have prompted to carry out in-depth studies and come out with solutions and policies which will go a long way in minimizing the damages caused by seismic ground motions. In this context, microzonation of urban areas have assumed new dimensions. Delhi, the capital city of India has a long seismic history and is being affected by local as well as by the Himalayan earthquakes. The Jabalpur urban agglomeration lies in the field of recurrent seismicity ascribed to the reverse activation of Son-Narmada South Fault. Dehradun, the capital city of Uttaranchal is located in the foot hills of Himalayas and is sitting on a tectonically isolated block confined between main boundary thrust & Himalayan Frontal Thrust. Macroseismic surveys of the earthquake effects have unraveled site-dependent ground amplifications increasing the vulnerability of the built environment to seismic hazards. Hence, a need is felt to carry out prognostic damage scenario of existing building stocks in urban area, review the existing codal provision of buildings so that appropriate disaster mitigation measures can be evolved. Keeping this in view, CBRI, Roorkee (India) has carried out studies to generate inputs on vulnerability of engineered and non-engineered structures and anthropic parameters of population living in dwelling susceptible to damage and other exposure factors for fourth level seismic risk microzonation with engineering seismological perspective. The paper briefly describes the microzonation studies initiated in India for Delhi, the capital city of India, Jabalpur & Dehradun, the capital of newly formed Indian state, Uttaranchal.
