This article generates hCard microformats, to make place-names and locations parsable by computers, either acting automatically to index articles, or via a user's browser tool, to (for example) add the subject to an address book. Within the hCard is a Geo microformat, to make the coordinates parsable, so they can be, say, located on a map, or sent to a GPS unit. See also Wikipedia's microformat project. hCard uses HTML classes including: "adr", "county-name", "fn", "label", "locality", "nickname", "note", "org", "region" & "vcard". Geo is produced by {{coord}}, and has classes: "geo", "latitude" & "longitude". Please do not rename or remove these classes. When giving coordinates, please don't be overly precise. |
Plutons
According to my understanding, Plutons are igneous formations, but they were not necessarily volcanoes, as they didn't necessarily erupt. Here are the plutons that I have found in the list so far: Whitevelcro (talk)
Malapai Hill
Malapai Hill is a Intrusive rock, which is an underground volcanic formation. I'm not sure whether this counts as a volcano. The rock is volcanic in origin, but it did not erupt. I believe it would be more reasonably categorized as a Pluton than as a volcano. I'd prefer a clarification from someone who knows more about geology or volcanology to make sure.

Alaska
Organization
Alaska has a lot of volcanoes that are parts of close groups or even stratovolcanoes, but there isn't any indication of this on the list. I don't see a precedent for smaller groupings of volcanoes on any of the other volcano lists, but it may be useful on a list this large.Whitevelcro (talk)
Cold Bay / Frosty Peak
Cold Bay Volcano listing here: No such thing, really. The coordinates given here are for Mt. Frosty, a volcano within the Cold Bay volcanic complex. Not sure how to go about renaming this link, however, as it goes to a "Cold Bay volcano" page.Idocrase 00:24, 26 January 2007 (UTC)
I fixed the Cold Bay Volcano problem by renaming the "Cold Bay Volcano" page to Frosty Peak Volcano and moving the relevant information (that wasn't plagiarized) from the Frosty Volcano page to Frosty Peak Volcano. In the process I learned that Frosty Peak is a stratovolcano, which means that it's made up of multiple older strata of previous volcanoes on the location, one of which is Frosty Volcano. I have two remaining concerns. One is that there were two different heights listed for the volcano, and I couldn't find a credible source for the taller one (the ones I found looked like they just copied and pasted from the Wikipedia page). The second is that it might be worth listing one of the older strata of Frosty Peak Volcano, Morzhovoi volcano on its own page. Whitevelcro (talk) 23:13, 9 June 2018 (UTC)
Buzzard Creek
I believe that Buzzard Creek is inappropriately linked. The main Wikipedia page references a small creek in South Dakota. The coordinates listed point to a nondescript semi-forested hillside in Alaska with no apparent volcano-like features in the near vicinity. In the absence of a suitable alternative name or evidence of the volcano I would advocate for removal, but I will wait for alternative opinions/guidance. 129.55.200.20 (talk) 17:35, 17 May 2018 (UTC)
I have now found that the volcano IS real, and IS named the Buzzard Creek caldera, but the link is not appropriate and is at a slightly different location. I am removing the link and updating the coordinates. 129.55.200.20 (talk) 17:38, 17 May 2018 (UTC)
Stepovak Bay 3
Stepovak Bay also has volcanoes 1, 2, and 4, which should perhaps be listed. Whitevelcro (talk)
Arizona
I am deleting Bonito Lava Flow from the list of volcanoes as it is a lava flow associated with Sunset Crater and not a volcano in its own right. See Geology of Sunset Crater National Monument --Burntnickel 15:06, 12 April 2007 (UTC)
Washington
White Chuck Cinder Cone
This may not be notable enough. There are a lot of small cinder cones in volcanic areas (for example, there are a bunch in the Simcoe Mountains area). So we may want to either remove cinder cones from the list, possibly including them in the articles for the larger volcanoes or the area where they are located. For example, this Cinder Cone is near Glacier Peak. Or, there may be a lot more small volcanoes to add to the list. In that case, we would want to add Dishpan Gap Cinder Cone and Indian Pass Cinder Cone, which are located near White Chuck.Whitevelcro (talk)
Microformats
I've added the hCard microformat to this page (class="vcard"); effectively wrapping the existing "Geo" microformat (in {{coord}}) with a name field (class="fn org"). Andy Mabbett 15:48, 16 April 2007 (UTC)
Too Many Entries?
I've been adding entries to the Arizona section and it is getting pretty big so I got to thinking, would it make sense to list individual vents and cones belonging to a particular volcanic field with that volcanic field rather than in this category? These would be features of a particular site of volcanism rather than unique volcanoes. Exceptions could be made if there is a compelling reason, if the site is a stratovolcoano or a case like Lassen Peak. Thoughts? --Burntnickel 00:38, 4 May 2007 (UTC)
- It might be better to just split this page in two alphabetically (A-M, N-Z, or whatever) . Andy Mabbett 14:52, 3 July 2007 (UTC)
Active?
I think it might be nice if the list mentioned whether the volcanoes are still considered active or not. —Preceding unsigned comment added by 221.186.127.18 (talk) 00:52, 27 February 2009 (UTC)
- That's actually a lot harder than it seems. Geologists don't actually classify volcanoes that way. It's more of an "evening news" sort of classification. See Talk:Mount_Hood#Dormant or active.3F for a discussion of whether Mount Hood is active or dormant. —EncMstr (talk) 00:56, 27 February 2009 (UTC)
Coordinates

The coordinates need the following fixes:
- Write here
89.60.169.109 (talk) 14:54, 13 June 2009 (UTC)I believe the Davidof volcanoe is located on Davidof Island and the coordinates
51°57'4.37"N 178°19'47.53"E would be more accurate.
Done, but used coordinates from http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Davidof. BrainMarble (talk) 02:56, 13 February 2010 (UTC)

Done, but used coordinates from http://www.avo.alaska.edu/volcanoes/volcinfo.php?volcname=Kiska. BrainMarble (talk) 03:07, 13 February 2010 (UTC)
Missouri
Could someone add the St. Francois Mountains to the list for Missouri. The area was volcanic 1 billion years ago. Thank you Magnum Serpentine (talk) 20:00, 5 September 2009 (UTC)
Done, using the following references:
- USGS: America's Volcanic Past, Missouri
- Missouri Department of Conservation, Directory of Missouri Natural Areas, St. Francois Mountains Natural Area
- Precambrian Volcanics Associated with the Taum Sauk Caldera, St. Francois Mountains, Missouri, U.S.A.

Maryland
If the list is going to include long dead volcanoes, can Garrett Island (Perryville, MD) be added? From what I've read, when it was active, it was an off-shore volcano. For that matter, the USGS says that there were volcanoes all over Virginia, the Carolinas, Georgia, Maryland, etc. Elemtilas (talk) 22:30, 15 June 2010 (UTC)
Lava fields
Why are there listings for lava fields? They aren't volcanoes, rather the product of a volcano. They should be removed since a list including lava fields would greatly expand what is already going to be an overwhelming list! Newberry Volcano in Oregon has probably hundreds of lava fields on it's flanks. But they all came from Newberry, a single volcano. If no one protests, I will begin removing listings for lava fields. Leitmotiv (talk) 22:39, 12 July 2010 (UTC)
Yellowstone Caldera
The list says it erupted 640,000 years ago but it has erupted about 10 times since then. The most recent eruption was something like 70,000 years ago and phreatic steam explosions have occurred in the lake - maybe more recently. Perhaps this should be noted in the list Senor Cuete (talk) 16:11, 22 April 2011 (UTC)Senor Cuete
- I've done so. --Avenue (talk) 00:19, 23 April 2011 (UTC)
Texas volcanoes
This does not mention the volcanoes of the Big Bend area. —Preceding unsigned comment added by 99.69.64.207 (talk) 14:30, 15 May 2011 (UTC)
Salton Buttes
The Salton Buttes should be added to the California list. The wikipedia article for them states they are considered active. 96.40.125.130 (talk) 22:41, 13 May 2018 (UTC)
