| Description |
The spate of Earthquakes in the country has heightened the sensitivity of
administrators, engineers and even lay people to risks due to earthquakes. Many
metropolitan and big cities in India are situated in the severe earthquake hazard threat in
the vicinity of Himalayan region and even in peninsular shield. On January 26, 2001, one
of the most destructive earthquakes ever to strike India occurred in the Kachchh region of
Gujarat in western India. The earthquake was of magnitude 7.7 (Mw) and the damage
was spread over a radius of 400 kilometers including major cities like Ahmedabad,
Bhavnagar and Surat at a distance of 240 km, 275 km and 350 km respectively. One can
not ruled out a similar threat to Delhi – the capital from local and probable catastrophic
earthquake due in central Himalaya. There are several other cities like Mumbai, Kolkata,
Dehradun, Guwahati and many more sitting in thick sedimentary basins along Indo-
Gangetic plane and Bramhaputra valley.
To mitigate the seismic hazard, it is necessary to define a correct response in
terms of both the peak ground acceleration and spectral amplification. These factors are
highly dependent on the local soil conditions and on the source characterization of the
expected earthquakes. This is the time to learn a lesson from Bhuj earthquake and to go
for a detailed seismic ground motion modeling for microzonation studies in large urban
areas and metroplotan cities of India. The present paper will discuss these issues, the
methodologies and some example of site-effects in Delhi city.
