All eruptions, explosive or nonexplosive, are accompanied by the release of volcanic gas. Most columns are straight with parallel sides and diameters from a few centimeters to 3 m.
The lava contracts as it cools, forming cracks. With this information although it might not be possible to prevent the erupting of a volcano at least the massive destruction of lives can be avoided by getting people evacuated in time.

It results in rich soil which is good for cultivation. Lava that is more sticky and less fluid moves slower. An event could be non-destructive without release of solids or magmatic liquid, or if there is anything to destroy, could be destructive with voluminous lava flows or explosive activity.

Common eruptions types are Plinian, Hawaiian, Strombolian, and Vulcanian. Gases come from the magma itself or from the hot magma coming into contact with water in the ground Columnar jointing forms in lava flows, sills, dikes, ignimbrites and shallow intrusions of all compositions.
The columns form due to stress as the lava.
