With the emergence of portable broadband seismic instrumentation, availability of digital
networks with wide dynamic range, and development of new powerful analysis techniques …

We consider the current state of our understanding of the rheology of two-phase magmas,
that is suspensions of either bubbles or crystals in a viscous silicate melt. The discussion is …

Over the last few decades, significant advances in using geophysical techniques to image
the structure of magma plumbing systems have enabled the identification of zones of melt …

Rhyolite magma has fuelled some of the Earth's largest explosive volcanic eruptions. Our
understanding of these events is incomplete, however, owing to the previous lack of directly …

Magma fragmentation is the breakup of a continuous volume of molten rock into discrete
pieces, called pyroclasts. Because magma contains bubbles of compressible magmatic …

Volcanic seismology represents the main, and often the only, tool to forecast volcanic
eruptions and to monitor the eruption process. This book describes the main types of seismic …

Using long-term data sets, the eruptive size, timing and style can typically be successfully
forecast for dormant volcanoes using current monitoring data and knowledge of precursory …

Magmas may flow or break depending on their deformation rate. The transition between
such viscous and brittle behavior controls the style of volcanic eruptions. While the brittle …

During the 2009 eruption of Redoubt Volcano, Alaska, gliding harmonic tremor occurred
prominently before six nearly consecutive explosions during the second half of the eruptive …

Volcanic eruptions are regulated by the rheology of magmas and their ability to degas. Both
detail the evolution of stresses within ascending subvolcanic magma. But as magma is …
