A pre‐eruptive increase of shear wave velocity, which correlates well with pre‐eruptive seismicity and dome‐growth is revealed. The method can be used as a “pressure‐gauge” for pressure changes inside of volcanoes, because increasing pressures in rocks are known to cause proportionally increasing elastic wave velocities.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380299452403675928","@type":"Researcher","foaf:name":[{"@value":"U.
