Yellowstone's supervolcano, nestled beneath Wyoming's expansive terrain and extending into Montana and Idaho, continues to draw intense scientific scrutiny. Recent seismic swarms and advanced imaging ...

For decades, volcanologists believed that the primary trigger for explosive eruptions was a drop in pressure as magma rises toward the surface. When pressure falls, gases dissolved deep within the ...

How do volcanoes work? What happens beneath their surface? What causes the vibrations—known as tremor—that occur when magma or gases move upward through a volcano's conduits? Professor Dr. Miriam ...

Over the past several months, periods of increased earthquake activity and ground deformation in the summit region of Kilauea volcano indicate that magma is accumulating beneath the surface. Where ...
