Template:Infobox eruption

File:Test Template Info-Icon - Version (2).svg Template documentation[view] [edit] [history] [purge]

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 {{Infobox mountain}}). The completely expanded form of the template is as follows:

<syntaxhighlight lang="wikitext" style="width:15em;"> </syntaxhighlight>

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!
image	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.
image_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 used for one day eruptions or when the start and end dates of an eruption are unknown.
start_date	Start date of eruption; should be as specific as allowable.
start_time	Start time of eruption; should be as specific as allowable.
end_date	End date of eruption; should be as specific as allowable.
end_time	End time 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.
area	Areal extent of lava or tephra released during an eruption.
volume	Amount of lava or tephra released during an eruption.
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. You can use a {{Location map}} template in place of a "hard" image map (use width = 250, with caption = )
map_size	Same as image_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:

1980 eruption of Mount St. Helens
File:MSH80 eruption mount st helens 05-18-80-dramatic-edit.jpg Photograph of the eruption column, May 18, 1980
Volcano	Mount St. Helens
Start date	March 27, 1980
Start time	12:36 p.m. PDT
Type	Phreatic, Plinian, Peléan
Location	Skamania County, Washington
VEI	5
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:

1914 eruption of Sakurajima
File:Kagoshima 1914.jpg The city of Kagoshima was covered by deep ash during the 1914 eruption of the Sakurajima, which is visible across the bay.
Start date	January 1914
Type	Peléan
VEI	4
Impact	Pre-eruption earthquakes killed at least 35 people; caused an evacuation and significant changes to the local topology.
