Internal geophysics (Physics of Earth's interior) Monitoring volcanoes using seismic noise correlations Surveillance des volcans apartir du bruit de fond sismique

In this article, we summarize some recent results of measurements of temporal changes of active volcanoes using seismic noise cross-correlations. We first present a novel approach to estimate volcano interior temporal seismic velocity changes. The proposed method allows to measure very small velocity changes (! 0.1%) with a time resolution as small as [
