説明

<jats:p>We infer temporal changes in the elastic properties of the edifice of Merapi volcano (Java, Indonesia) before its eruption in 1998 by analyzing multiply scattered elastic waves excited by a repeatable controlled seismic source. 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>
