Hi, Ifm Keisuke Yoshida, an associate professor at Tohoku University, Japan.
I am interested in understanding earthquake occurrence, source properties, and seismicity patterns in relation to the spatiotemporal evolution of stress and strength.
This is a challenging topic, as it is currently not possible to estimate the absolute magnitude of stress at depth from seismological or geodetic data.
To address this, I have been attempting to extract information on the evolution of stress and strength by combining data analysis with elastic theory, and to explore its relationship with earthquake generation.
Many of the results obtained through these analyses are available via the data page, and I hope they will be of use to others.
Note on the Paper Investigating the Generation Mechanisms of the 2023 Noto Peninsula Earthquake Swarm (Yoshida et al., 2023, JGR):
There is a typographical error in our previous paper (Yoshida et al., 2023, JGR) related to the expression used in Section 3.
It states that the curves in Figure 8 were computed using the equation D = (4Dt), but they were actually calculated using D = (4Dt).
To convert the plotted diffusion coefficient into the more commonly used form with a factor, please divide the reported values by .
We thank Dr. M. Nakatani for kindly pointing out the error.
