1. 13:30-13:45
TITLE: Broadband observation of crustal activity using a laser strainmeter network
AUTHOR: Akito ARAYA・*Akiteru TAKAMORI, Akio KATSUMATA (U. Toyama), Makoto OKUBO (Kochi U.), Takeo ITO (Nagoya U.), Hirotaka TAKAHASHI (Tokyo City U.), Satoshi ITABA (AIST), Tatsuki WASHIMI (NAOJ) and Takaaki YOKOZAWA (ICR0R, U. Tokyo)
2. 13:45-14:00
TITLE: Simultaneous Bayesian estimation of multisegment fault geometry and complex slip distribution: application to the 2024 Noto Peninsula earthquake
AUTHOR: *Kai NAKAKO・Tsuyoshi ICHIMURA, Hiroshi MUNEKANE・Tomokazu KOBAYASHI (GSI), Takane HORI (JAMSTEC) and Kohei FUJITA
SUMMARY: In this study, we developed a Bayesian estimation method that simultaneously estimates fault geometry and coseismic slip distribution for earthquakes involving complex slip. In this presentation, we will introduce the estimation method and an application example on the 2024 Noto Peninsula earthquake.
