What happens after a volcanic eruption??
This is a complex question that you would like a simple answer to. First of all there are different types of eruptions as well as magnitudes of eruptions. When the molten rock is reased it can result in pyroclastics (molten rock that is ejected into the air and then solidifies), or a pseudo liquid flow that consist of heated air, heated particles that flows rapidly down the volcanoe. Ignimbrites are pumice-dominated pyroclastic flow deposits with subordinate ash.There are many historic examples, most of which are restricted to valleys emanating from summit craters. One such deposit from the 1980 eruption of Mt. St. Helens (below left) contains abundant pumice blocks at its terminus. However, there are no historic examples of the voluminous ignimbrite sheetflows associated with caldera formation. These extensive deposits can cover many thousands of square kilometers.Then ther is the ejected ash that goes into the atomoshere to deal with, its effect is dependent on the volume ejected. Wa
