As part of the Center for Infrastructure Renewal’s Seminar Series, Dr. Hemanta Hazarika with Kyushu University, Japan, provided a talk on “Earthquake Induced Fluidized Flow in Ground with Gentle Slopes”. The 2018 Sulawesi (Indonesia) earthquake triggered long distance fluidized failure associated with the liquefaction of gentle slopes. Based on field reconnaissance, the topography, geology, and ground structure are quantitatively evaluated. Also, through laboratory soil tests, model experiments, and numerical simulations, the mechanism of slip vulnerability of low-gradient ground is clarified.

Dr. Hazarika is currently a professor in the Graduate School of Engineering and Department of Interdisciplinary Science and Innovation, Kyushu University, Fukuoka, Japan. He obtained his Bachelor of Technology (B. Tech) degree in Civil Engineering from the Indian Institute of Technology (IIT), Madras, India in 1990. He obtained his master’s degree in Geotechnical Engineering in 1993 from Nagoya University, Japan and Ph. D. from the same university in 1996. Currently, he is also adjunct professor of IIT Madras, India.

Dr. Hazarika’s research activities include disaster prevention and mitigation, soil-structure interaction, stability of soil-structures during earthquakes and tsunami, ground improvement, application of recycled waste and lightweight materials in constructions, stability of cut slopes, and landslides and their protection.

We were honored to have Dr. Hazarika provide his lecture to faculty, staff, and students at the CIR.
