Abstract
The Murono mud volcano is one of three in Matsudai, Niigata Prefecture, Japan. Significant ground uplifts have been observed at least three times （2007 Niigataken Chuetu-oki Eqrthquake; 2001 Naganoken Hokubu Earthquake; 2014 Naganoken Kamishiro Fault Earthquake） in conjunction with large-scale earthquakes. The 2024 Noto Peninsula earthquake occurred on January 1, 2024. We conducted leveling surveys at the Murono mud volcano two months prior and half a year after the earthquake. The results showed that the entire Murono mud volcano experienced a maximum uplift of 162 mm during the period from November 2023 through June 2024. This uplift is considered to have been caused by the main shock of the 2024 Noto Peninsula earthquake, and the cracks are considered to have been caused by this uplift. In the future investigations, we will focus on the underground phenomena that caused this uplift.
