Sedimentological and micropaleontological characteristics of tsunami deposits associated with the 2024 Noto Peninsula earthquake.

ABSTRACT: This study reports sedimentological and paleontological features of deposits left by the 2024 Noto Peninsula tsunami in Suzu City, Japan. Tsunami deposits were found up to 70 m inland from the post-tsunami shoreline along our transect. The tsunami deposits were collected at five locations for observation by Soft X-ray and CT images, grain-size analysis, and diatom analysis. Soft X-ray and CT images identified that the five stratigraphic units (Units 1-5) at the most seaward location (SZ1) and deposits with faint laminae at the other locations (SZ2-4). Grain-size analysis showed that the tsunami deposits generally composed of fine to very fine sand at all sampled locations. At SZ1, Unit 3 exhibits climbing ripples with their leeside seaward. The ripple tops were probably dragged seaward. Th
