On January 1st, 2024, an earthquake occurred in the Noto region of Ishikawa Prefecture. This earthquake caused damage to many buildings, mainly in the northern part of the Noto Peninsula. It is necessary to clearly determine the destructiveness of earthquake motions. In the previous research, collapse base share coefficient (Cc) spectra to prevent buildings from being collapsed by the earthquake motions were proposed as a method for evaluating the destructiveness of earthquake motion.
In this study, in order to consider the destructiveness of the ground motions of the Noto Peninsula Earthquake, seismic response analyses were performed, and the Cc spectra were obtained. There were general correlations between Cc spectra and building damage. By comparing the Cc spectra of the 1995 Hyogo-ken-Nanbu Earthquake (JMA Kobe), the characteristics of the destructiveness of the Noto Peninsula earthquake were considered.
