Subduction-zone stratovolcanoes, such as Mount St. Helens, Mount Etna, and Mount Pinatubo, typically erupt with explosive force: the magma is too stiff to allow easy escape of volcanic gases. As a consequence, the tremendous internal pressures of the trapped volcanic gases remain in the pasty magma.

The eruption is the first of 2014 after a particularly active year in 2013, a result of a new crater forming on the southeastern side of the volcano. Aside from the airport closure, there was minimal disruption on Sunday.
