Editing Volcanic explosivity index (section)

==Limitations==
Under the VEI, [[Volcanic ash|ash]], [[lava]], [[volcanic bomb|lava bombs]], and [[ignimbrite]] are all treated alike. [[Density]] and [[Vesicular texture|vesicularity]] (gas bubbling) of the volcanic products in question is not taken into account. In contrast, the DRE ([[dense-rock equivalent]]) is sometimes calculated to give the actual amount of [[magma]] erupted. Another weakness of the VEI is that it does not take into account the power output of an eruption, which makes the VEI extremely difficult to determine with prehistoric or unobserved eruptions.

Although VEI is quite suitable for classifying the explosive magnitude of eruptions, the index is not as significant as [[sulfur dioxide]] emissions in quantifying their atmospheric and climatic impact.<ref name=JRMS>{{cite journal  |last1=Miles |first1=M.
