Abstract

In the Muro district of Uchinada Town, which suffered significant liquefaction damage during the 2024 Noto Peninsula Earthquake, an on-site investigation was conducted to understand the damage situation as part of a basic study aimed at elucidating the mechanism of liquefaction damage. Furthermore, past topographical maps and geological survey results were collected to comprehend the history of reclamation by drainage and the composition of the ground in the Muro district. As a result, it was confirmed that the residential areas on the reclaimed land side of the Muro district, which experienced notable liquefaction damage, are composed of dune layers and landfill layers resulting from reclamation by drainage.
