Destroying a volcanic edifice - interactions between edifice instabilities and the volcanic plumbing system

Book Contribution - Chapter

Volcanic edifices can collapse during their lifetime, often more than once. Volcano collapses have been documented worldwide in various tectonic settings. They can affect small and large edifices and active or non-active volcanoes. Long- or short-term instabilities develop within or below the edifice, deform its shape and a sudden trigger might prompt volcano failure, resulting in a volcanic landslide. The volume portion of the edifice involved in the collapse can vary from ∼0.1 to 10 km3 and depends on the size of the edifice and the location of the failure plane. A shallow-seated failure plane will likely not affect the volcanic plumbing system, while a deep-seated failure plane may impact the structure and the orientation of the volcanic and igneous plumbing system and can influence the post-collapse volcanic activity and type of erupted magma. This then influences how an active edifice can rebuild itself.
