Abstract We have analyzed 16 earthquake waveform data recorded during the period from 2006 to 2013 at broadband station lying at the premises of Indian School of Mines, Dhanbad in the Eastern Indian Shield region. Coda window lengths of 30, 40 and 50 s were selected after thorough analysis of the waveforms. The Coda Q (Q$_{c}$) values were computed using single back scattered method. The earthquakes parameters were compiled from catalogue of Indian Meteorological Department (Nodal agency under Govt. of India for record keeping and data sharing), New Delhi. The estimated average Q$_{c}$ values for three coda windows 30, 40 and 50 s are Q$_{c}$ = 259.1f$^{0.808}$, Q$_{c}$ = 275.9f$^{0.764}$ and Q$_{c}$ = 397.1f$^{0.651}$, respectively. The average Q$_{c}$ value estimated from the Q$_{c}$ values for the time windows 30, 40 and 50 s is found to be Q$_{c}$ = 313.2f$^{0.73}$. Thus, the attenuation follows the power law relationships (e.g., Q$_{c}$ = Q$_{0}$f$^{n}$), and the moderate to higher values of frequency parameters (n) obviously show that the Q$_{c}$ value is a strong function of frequency. The increasing values of Q$_{0}$ with increasing lapse time indicating the depth dependency of attenuation, and accounts for decreasing heterogeneity towards deeper level beneath the study area.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
