Volcano Watch — Magma chamber music can tell a revealing tale

Disturbances to a magma or lava body—such as Kīlauea Volcano’s underground summit magma reservoir or its current lava lake—can occur for a variety of reasons, including rising gas pockets or the fall of wall rocks into a lava lake. When a body of magma or lava is disturbed, the fluid in it can respond by vibrating or sloshing in a variety of ways.
