Modern geophysical techniques enable changes to be observed at some volcanoes before magmatic eruptions: detection of seismicity (see “ Seismic Monitoring of Volcanoes”) from magma pushing through cold country rock is one of the most common and successful monitoring techniques and can lead to short-term forecasting (see “ Volcanic Eruptions, Real-Time Forecasting of”). Another example of geophysical precursors to eruptions is surface deformation from inflation or deflation of a volcano due to magma movement. However, some volcanoes do not display these clues, and there remains a need for techniques that are sensitive to other physical attributes that might change in conjunction with the...
