Wikipedia:WikiProject Volcanoes/Categorization

Volcanoes and structures

• Ensure that the article in question has the correct country-specific, region-specific, or ocean-specific volcano category, e.g. :Category:Volcanoes of the United States, :Category:Volcanoes of Mars, :Category:Volcanoes of the Atlantic Ocean.
• If it is not in the appropriate list article, such as List of volcanoes in New Zealand, List of extraterrestrial volcanoes, etc. (see :Category:Lists of volcanoes for current choices), add it (free deorphaning).
• Next, please ensure that it has the correct volcanic type categories (one or more, in some cases):

Volcanic eruptions

• Articles about a particular volcanic eruption should be listed in :Category:Volcanic events, while articles about types of volcanic eruptions are listed in :Category:Volcanic eruption types.

Volcanic lakes

• Articles about lakes located within volcanic craters and calderas are listed in :Category:Crater lakes. Which has grown to contain over 200 articles, and it is already perhaps the most comprehensive list of crater lakes available anywhere. A convincing demonstration of the power and magic of Wikipedia!

General topics

• Articles about general topics in volcanology may be listed in :Category:Volcanology.

Volcanology

• Articles about notable volcanologists/vulcanologists are listed in :Category:Volcanologists.

A useful tool for categorization work is HotCat, which allows you to edit in cats from a dynamic list on the page by clicking on the categories bar.

It is important that volcano names which begin with "Mount" or "Volcán" or some such words are sorted based on their actual name, not the generic prefix. The easiest way to ensure this for all categories in an article is to place the magic word {{DEFAULTSORT:}} before the category tags. This will apply the sort key to all categories at once, without having to enter something like "|Rainier, Mount" in several category tags. See Template:DEFAULTSORT for more info.

• A comprehensive cleanup of the subcategories in :Category:Volcanoes was undertaken during the first weeks of this project, since previously entire trees like :Category:Archipelagoes (every island group in the world?) and :Category:Saint Helena (including every single thing about this little island) had been mis-filed as subcategories of :Category:Volcanoes by ocean. Most category problems and errors have now been fixed, and any other new or unfixed errors should be taken care of as they are found.

Category trees are dynamically-generated categoritical structures (they require JavaScript to be enabled), press the [+] to expand them. The main listing can be found using [http://en.wikipedia.org/w/index.php?title=Special%3ACategoryTree&target=Volcanology&mode=categories], and see mw:Extension:CategoryTree for more info.

Following category discussions, the volcano lists have been listed under their respective categories (eg. List of volcanoes in Antarctica is categoriezed under :Category:Volcanoes of Antarctica.
