R.D.Oldham of GSI, was the founder of modern seismology, whose systematic account of the Great Assam Earthquake (1897) is the first well recorded earthquake of the world. Since then GSI was actively involved in scientific records and studies whenever earthquake broke out in any parts of India or adjacent areas. After independence, GSI took a stride by providing inputs for aseismic design of major civil engineering projects specially in the seismically active sub-Himalayan region. In 1986, a separate division was set up at Lucknow and identified as a Centre for Geoseismology & seismotectonic Studies. Subsequently sub-centres were set-up in eastern and north-eastern regions,. Later, after the devastating earthquake at Killari in 1993 two more centres were set-up at Hyderabad (SR) and Nagpur (CR) for seismotectonic evaluation of peninsular India. All those units are collecting and monitoring the data related to Geoseismicity.
Macroseismic survey carried out by GSI for a number of post earthquake damage has been summarized and published in the form of GSI Special Publication.
