Although volcanic eruptions are spectacular natural events that occur around the world every day, most volcanoes spend the majority of their time not erupting. To accurately forecast volcanic activity ...

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped ...

LMU volcanologists decipher the behavior of magma beneath an active volcano and reveal how it reacts to drilling. Although volcanic eruptions are spectacular natural events that occur around the world ...

Learn how stress inside a volcano can make gas bubbles form early, helping explain why some eruptions stay quiet instead of exploding. One of the most explosive volcanoes in U.S. history began its ...

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 ...

During magma vesiculation, permeability is established when growing bubbles form connected networks which allow fluids to percolate. This percolation threshold controls the relative rates between ...
