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 in 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 at convergent and divergent plate boundaries.[1] Sector collapses are generally very sudden; however, some attempts have been made to predict collapse events.
