On January 1, 2024, at 16:10 JST, a powerful earthquake with a moment magnitude of 7.5 struck the Noto Peninsula in southeastern Japan, with the epicenter in Suzu City, Ishikawa Prefecture. The earthquake brought extensive devastation to the prefectures of Ishikawa, Fukui, Toyama, and Niigata. Low-rise buildings, roads, utilities, port facilities, and other essential infrastructures sustained significant damage. Slope and embankment failures disrupted the transportation network on the Noto Peninsula, hampering the recovery efforts. The earthquake also triggered severe soil liquefaction, leading to widespread geotechnical and structural damage. Liquefaction was not limited to coastal areas near the epicenter; it was observed in more distant parts of Ishikawa Prefecture and in the neighboring prefectures as well. The town of Uchinada, Ishikawa Prefecture, with its gently sloped reclaimed land, was particularly hard hit, with significant lateral spreading causing massive damage to low-rise buildings, roads, and public utilities. To better understand the mechanism behind the widespread liquefaction and its associated damage in Uchinada Town, a joint investigation team comprising researchers and engineers from academia, government, and industry was formed a month after the earthquake. The team conducted several surveys in Uchinada Town and nearby areas between February and August 2024. This paper presents the detailed findings of the investigation, along with a factorial analysis of the extensive lateral displacement that caused damage to infrastructures.
