No Such Thing as a Dormant Volcano? Magma Chambers Awake Sooner Than Thought

- ScienceDaily (Mar. 6, 2011) — Until now it was thought that once a volcano's magma chamber had cooled down it remained dormant for centuries before it could be remobilized by fresh magma. A theoretical model developed by Alain Burgisser of the Orléans Institute of Earth Sciences (Institut des Sciences de la Terre d'Orléans -- CNRS/Universités d'Orléans et de Tours) together with a US researcher , was tested on two major eruptions and completely overturned this hypothesis: the reawakening of a chamber could take place in just a few months. This research should lead to a reassessment of the dangerousness of some dormant volcanoes. Full story:
