Ravi Jakka
Dr. Ravi Sankar Jakka has contributions in various fields of Geotechnical Earthquake
Engineering. He was involved in the preparation of national level technical document,
“Geotechnical/geophysical investigations for seismic microzonation studies of urban centres in
India” for NDMA. He had carried out extensive investigations on dynamic soil properties and
liquefaction resistance of pond ash and come up with guidelines on use of pond ash as
geotechnical earth material in high seismic regions. He has guided a PhD student on
uncertainties in surface wave methods on geotechnical site characterization. Studies have
been conducted on uncertainties arising from the field measurements and inversion, and the
results are published in reputed international journals. He is currently guiding a PhD and few
M.Techo dissertations on local site effects. Few are on the effect of bedrock depth and type on
site response and classification. Others are on deep soil effects on site amplifications
particularly on Indo-Gangetic basin. Outcomes of these dissertations, are presented at
international conferences and published in reputed journals. He is also guiding PhD and M.Tech
dissertations on various other important aspects of geotechnical earthquake engg. such as
earthquake resistant design of foundations on sloping grounds, post-liquefaction behavior
of silty sands, geotechnical hazard assessment of hill slopes, development of earthquake
early warning for Northern India, etc. He had also developed a new formulation in isochrone
back projection during his post-doctoral research at Univ. of California, Riverside to quickly
arrive at the source characterization (slip distribution as well as their magnitudes) using nearsource ground motions.
