Abstract
An exponential rise in population along with uncontrolled and unplanned urbanization exposed to earthquakes reeks a plenitude of hazard in terms of life and property. Effects, mechanics, and impact of an earthquake in terms of ground shaking, site effects, liquefaction, and landslides had been broadly covered in the past, and the recent developments have catered profound understanding of earthquakes. Our recent studies on ground motion attenuation characteristics, comprehensive seismic hazard analyses, site effects, liquefaction behaviour, seismic microzonation, ground motion analyses, joint time–frequency analysis-based ground motion synthesis, etc., have largely contributed to geotechnical earthquake engineering. Our detailed experimental and numerical works on liquefaction have improved the understanding of liquefaction of sands. Installation of ground motion sensors and monitoring of earthquakes have further supplemented geotechnical earthquake engineering research in the country. Recent surveys on earthquake preparedness and readiness indices have pointed out the urgent need for general awareness, and an action plan towards mitigating and managing the hazard due to earthquakes. This paper discusses the Quintessence of 25 years of the author’s contribution to the field of Geotechnical Earthquake Engineering.
