Seismic monitoring is the most used technique for volcano surveillance.
Deformation measurements at Long Valley Caldera
When magma moves into a volcanic system, and closer to the surface of the earth, the area surrounding the volcano may move upward and outward. This swelling is typically measured using the Global Positioning System (GPS) and tiltmeters (tilt).
Gas Monitoring at Long Valley and the Surrounding Region
By monitoring the relative abundances of carbon dioxide (CO2) and sulfur dioxide (SO2), scientists may be able to infer magma movement through the volcanic system.
