In the most explosive eruptions, the eruption column may rise over 40 km (25 mi), penetrating the stratosphere. Stratospheric injection of aerosols by volcanoes is a major cause of short-term climate change. See more An eruption column or eruption plume is a cloud of super-heated ash and tephra suspended in gases emitted during an explosive volcanic eruption. The volcanic materials form a vertical column or plume that may rise many … See more The solid and liquid materials in an eruption column are lifted by processes that vary as the material ascends: • At … See more Column collapse Eruption columns may become so laden with dense material that they are too heavy to be supported by convection currents.
