Welcome to Yasunori Sawaki’s homepage!

My name is Yasunori Sawaki (Ph.D., he/him), a post-doctoral researcher in Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST). I am an early-career researcher in seismology (a study of earthquakes and interior strucure of the Earth), who earned a Ph.D. (Science) from Kyoto University (in Japan) in March 2023. My current work is to estimate the detailed geometry of crustal faults and the seismological heterogeneity in crusts and subducting slabs, with the aim of advancing our understanding of seismotectonics.
