Iwata City, Shizuoka Prefecture, JapanThe boiling sand and boiling water in the Otagawa Lowland by the 1944 Tonankai earthquake were studied byquestionnaire survey. The number of boiling sand and boiling water was 796. The boiling sand and boiling water
are mainly generated in the southern part of the Otagawa lowland, and are concentrated in the old river channel,
low natural levee and relatively low sand dunes along the Enshu-nada coast, which are considered to be prone toliquefaction. Liquefaction of a muddy ground is often caused by the presence of a buried sand layer underneath.
Keywords: boiling sand, boiling water, 1944 Tonankai earthquake, liquefaction, Otagawa Lowland.
