Welcome to Yasunori Sawaki’s homepage!
My name is Yasunori Sawaki (Ph.D., he/him), an assistant professor at Ritsumeikan University, Japan. 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.

Our new paper on fault geometries of the 2024 Mw 7.5 Noto Peninsula earthquake
was published in Journal of Geophysical Research: Solid Earth!

I was awarded “Doctor of Philosophy in Science” by Kyoto University on March 23, 2023.
The title of my PhD dissertation is “Heterogeneous seismic structure in onshore and offshore areas of the Nankai subduction zone with receiver-side responses to regional deep-focus and teleseismic earthquakes”.
In the middle of March 2023, Slow-to-Fast Earthquake Workshop was held in Taiwan and
I had a poster presentation “Impedance contrast in the Nankai subduction zone”.
I finally published my homepage!

A03 group for Slow-to-Fast Earthquake held a workshop in Beppu city in Feb 9–11 2023. I had a talk about the spatial relationship of slow earthquakes and seismic impedance contrasts in the Nankai subduction zone.
Publication list was created. CV was created. Links was created.
The defense of my PhD thesis was held on Jan. 16, 2023. It was the greatest moment ever in my research life.
This is the first post. I’m testing the English page.
