Deformation monitoring at Mammoth Mountain
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). The GPS receivers near Mammoth Mountain are part of the 46 instruments that make up the Long Valley Caldera deformation monitoring network.
