I participated in the Japan Geoscience Union (JpGU) Meeting 2024 , held at the Makuhari Messe in Chiba, JP, from May 26 to 31. I made two presentations: one for oral and the other for poster.

• [SCG50-02] Multiscale Fault Estimation in California and Oklahoma. Sawaki, Y., D. Shelly, T. Uchide, K. Sagae, T. Shiina, Y. Sato, and H. Horikawa
• [U15-P09] Fault geometries of the 2024 Noto Peninsula earthquake estimated by hypocenter clustering. Sawaki, Y., T. Uchide, T. Shiina, K. Sagae, H. Horikawa, and K. Imanishi

We have a new preprint on the seismic structure beneath the Kii Peninsula, southwestern Japan, available on SSRN. While it’s not yet peer-reviewed, feel free to check it out if you’re interested!

SF-A03 Group Workshop at Toyama was held from Feb. 08–10, 2024. I gave a talk about “Hypocenter-based Visualization of Multiscale Earthquake Faults”.

The presentations on geology related to the mechanism of tectonic tremors were interesting to me. As a research collaborator of group A03, I would like to contribute to the comparative subduction zone studies of Slow-to-Fast earthquakes!

Happy New Year! I hope you all have a great year!

I participated in the AGU Fall Meeting 2023 held at San Francisco during December 11–15. We had a good poster presentation with lively discussions with worldwide researchers. I can’t wait the next opportunity to interact with you all!

I visited the United States Geological Survey in Golden, CO for a month and conducted collaborative studies with Dr. David Shelly. It was a fantastic stay and a good opportunity to proceed my research.

I’m going to San Francisco for the upcoming meeting of American Geophysical Union. I have a poster presentation related to my current study .

Our new paper is publishded! We analyzed shear wave splitting from receiver functions in Shikoku Island, SW Japan, and along-dip variation of fast axes is clarified. Check it out!

I joined the 2023 SSJ Fall Meeting held in Yokohama and made a poster presentation.

I earned Grant-in-Aid for Research Activity start-up, Japan Society for the Promotion of Science (Grant Number 23K19077).

I visited Tohoku University Aobayama Campus for a scientific meeting. This made me feel nostalgic.
