Bernard A. Chouet 2006 <p class="p1">At an active volcano, Very-Long-Period (VLP) seismicity (with typical periods in the range 2-100 s) reflects pressure fluctuations resulting from unsteady mass transport in the sub-surface plumbing system, and hence provides a glimpse of the internal dynamics of the volcanic edifice. Understanding the fundamental fluid-flow mechanisms involved in the generation of VLP seismic events is, therefore, key to improving eruption prediction and developing insight into the dynamics of fluid movement in volcanoes.</p> application/pdf en Bureau de recherches géologiques et minières Modelling and understanding volcanic processes using high-quality seismological data article
