Much like the main arteries carry the blood around the human body, a volcanic conduit does the same for magma within a volcano. However, while it is well understood how changes to the blood flow within an artery effects recorded data such as a pulse or a person’s blood pressure, the extent to which changes in magma flow properties effect data recorded on volcanoes is not as well-constrained. Is it possible that a small change in magma temperature or water content could be recorded on geophysical monitoring instruments? What effect does the size of gas bubbles within the magma have on the overall volcanic system? These, and questions like them, are being addressed within the volcanic studies group using state-of-the-art computer models. By obtaining an improved knowledge of the processes that occur deep within a volcano we are able to better understand what is causing changes in the observed data recorded at the surface. Through correct interpretation of a volcano's vital signs we hope to aid volcanic observatories in eruption prediction and reduce the risk to populations surrounds active volcanoes.
