Yoshimichi Tsukamoto graduated from The University of Tokyo in 1990, and received his Ph.D. from the University of Cambridge in 1995. He then moved to the Tokyo University of Science as a research associate in 1995, where he became a full professor in 2012. Kenji Ishihara is a professor emeritus of The University of Tokyo, where he had spent his research career focusing on the subject of soil liquefaction in geotechnical engineering until his retirement there in 1995. He then moved to the Tokyo University of Science as a professor in 1995 and continued his research career with Yoshimichi Tsukamoto, the co-author of this book. He then moved to Chuo University as a professor in 2001. The two authors have devoted their research careers mainly to the subject of soil liquefaction during the period from 1995 to date. They have made great developments and published many technical papers, including field case history studies from the recent major earthquakes in Japan.

• Liquefaction resistance of saturated sand.- Characterising undrained monotonic behaviour of saturated sand.- Characterising undrained behaviour of imperfectly saturated and unsaturated sands.- Analysis on triggering of soil liquefaction including effects of imperfect saturation.- Use of in situ sounding tests for evaluating soil liquefaction triggering.- Evaluating post-liquefaction settlement and lateral deformation.- Use of in situ sounding tests for evaluating stability of soil deposits subject to liquefaction.
