Abstract A moment magnitude ( M w ) 7.5 earthquake occurred on January 1, 2024, at the northern tip of Noto Peninsula, Central Japan, triggering a large tsunami. Seismological and geodetic observations revealed rupture mapped submarine active faults. While proximal segment ruptures have been well resolved by previous research, far offshore segments posed challenges for onshore-based inversions. This emphasizes necessity comprehensive study fault through tsunami modeling. Here, we aimed to...
<title>Abstract</title> A moment magnitude (M<sub>w</sub>) 7.5 earthquake occurred on January 1, 2024, at the northern tip of Noto Peninsula, Central Japan, triggering a large tsunami. Seismological and geodetic observations revealed rupture mapped submarine active faults. While proximal segment ruptures were well resolved by existing researches, distal segments posed challenges for onshore tsunami observations, prompting need comprehensive study wave sources. We aimed to examine propagation...
Abstract A quantitative understanding of paleotsunamis is a significant issue in tsunami sedimentology. Onshore deposits, which are geological records inundation, used to reconstruct paleotsunami events. Numerical models hydrodynamics and tsunami-induced sediment transport utilized such reconstructions connect deposit characteristics, flow conditions, (paleo-) sources. Recent progress numerical modeling has increased the possibility developing methodology estimate sources from deposits....
