Collapse of a volcano / From Wikipedia, the free encyclopedia
A sector collapse or lateral collapse is the structural failure and subsequent collapse of part of a volcano. Unlike a flank collapse, a sector collapse involves the central volcanic pipe. Sector collapses are one of the most hazardous volcanic events[2], often resulting in lateral blasts[1], landslides[3], and changes volcanic eruptive behavior. Sector collapse can be caused by earthquakes[3], volcanic eruptions[1], gradual volcanic deformation[1], and other processes. Sector collapse events can occur on volcanoes present at both convergent and divergent plate boundaries[1]. Sector collapses are generally very sudden, however some attempts have been made to predict collapse events.
Sandbox
This is the sandbox page where you will draft your initial Wikipedia contribution.
If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content.
