This infobox is meant to be used on pages about volcanic eruptions and on the sections of articles about a volcano about an eruption, but not as the main template on the pages of the volcanoes themselves (for that, use Template:Template). The completely expanded form of the template is as follows:

{{Infobox eruption
 | name =
 | photo =
 | photo-size =
 | caption =
 | date =
 | volcano =
 | type =
 | location =
 | coordinates =
 | VEI =
 | map =
 | location-map =
 | map-size =
 | map-caption =
 | impact =
}}

Field name	Input
name	Name of the eruption. The conventions for naming relatively modern eruptions is to use "[Year] eruption of [volcano]". See for instance 1980 eruption of Mount St. Helens. If the timing is incomplete (common for extremely old eruptions), use as specific a time period as you may in place of the year. Many eruptions have names given to them by the scientific community, if one exists, use it!
photo	Photo of the eruption. A painting or other representation may be used for eruptions preceding the invention of photography. Precede filename with "File:" but do not use [ ] brackets.
photo-size	Size of the photo; leaving this blank will cause it to default to 250px.
caption	Caption for the photo.
date	Date of eruption; should be as specific as allowable.
volcano	Name of the volcano where the eruption occurred.
type	Type of eruption, see Types of volcanic eruptions for the different types.
location	Location of the volcano, e.g. "Boulder Springs, Colorado"
coordinates	Coordinates of the volcano. Use Template:Coord.
VEI	Volcanic Explosivity Index, a measure of an eruption's strength similar to the Richter scale; the type of eruption can be inferred off its VEI, and this field also automatically adds the volcano to the respective "VEI-level volcanoes" category.
map	Map of the eruption, if there is one.
location-map	Allows you to use the Template:Template template in place of a "hard" image map. Note that the template automatically aligns left, so you should not make it less then 250px wide.
map-size	Same as photo size, above.
map caption	Caption for the map.
impact	What was the impact of the eruption? How many lives were lost? How much property damage? What was the impact of the eruption on the local and global landscape? Basically, why is the eruption notable?

Here is an example usage:

created with this source:

{{Infobox eruption
| name = 1980 eruption of Mount St. Helens
| photo = File:MSH80 eruption mount st helens 05-18-80-dramatic-edit.jpg
| photo-size = 200px
| caption = Photograph of the [[eruption column]], May 18, 1980
| date = May 18, 1980
| volcano = [[Mount St. Helens]]
| type = [[Plinian eruption|Plinian]]
| location = [[Skamania County, Washington|Skamania County]], 
  [[Washington (state)|Washington]]
| coordinates = {{coord|46|12|1|N|122|11|12|W|display=inline}}
| VEI = 5
| map = File:St helens map showing 1980 eruption deposits.png
| map-size =
| map-caption = Map of eruption deposits
| impact = 57 deaths, $1.1 billion in property damage; 
  caused a partial collapse of the volcano's flank, 
  deposited ash in 11 states
}}

This template can also be used inside an article, in a section dedicated to an important volcanic eruption. In these cases, the volcano, location, coordinates, and map should be left out, as they are redundant to the main article infobox (presumably Template:Infobox mountain). For instance:

Source:

{{Infobox eruption
 | name = 1914 eruption of Sakurajima
 | photo = Image:Kagoshima 1914.jpg
 | photo-size =
 | caption = The city of [[Kagoshima]] was covered...
 | date = January 1914
 | volcano = 
 | type = [[Peléan eruption|Peléan]]
 | location =
 | coordinates =
 | VEI = 4
 | map =
 | location-map =
 | map-size =
 | map-caption =
 | impact = Pre-eruption earthquakes killed at least 35 people;...
}}
