Short summary
Changes to a volcanic edifice and its surroundings can be caused by movements of underground magma, gas or other fluids (typically water). These deformations are usually very small in magnitude, so very sensitive instruments are the only capable of detecting them. A discrimination between deformations caused by volcanic processes in regards to those caused by external sources could help in understanding the volcano dynamics and give scientists a way to forecast volcanic eruptions.
