[edit] Ring of Fire

Hi Edziza,

Thanks for joining WikiProject Volcanoes and helping out with volcano-related articles here. We can always use more knowledgeable and experienced contributors. However, User:Black Tusk was worried about some of your edits which state that Canadian volcanoes in the NCVP are not part of the Pacific Ring of Fire. It seems that you are taking a very narrow definition of the Pacific Ring of Fire, by including only subduction-related volcanoes. But most references take a broader, more inclusive definition which would include volcanoes in extensional rifting areas like the NCVP and also most of the western USA other than the Cascades (i.e. southern California, Arizona, New Mexico) as part of the Ring. Some refs even include the rifting-related volcanoes in Antarctica as part of the Ring of Fire. Personally, I prefer the broad inclusive definition. The Pacific Ring of Fire is largely an artificial construct anyway (more popular than scientific), so there is no harm in being inclusive as long as reliable references support it.

In only a few minutes of searching, I found two reliable refs which support including all Canadian volcanoes as part of the Ring. The Geological Survey of Canada Volcanoes of Canada website states that "In Canada, young volcanoes occur in British Columbia and the Yukon Territory and are part of the system of volcanoes found around the margins of the Pacific Ocean that has long been referred to as the 'Pacific Ring of Fire'." In the book Volcanoes of North America, the section "Volcano Tectonics of Canada" (p. 112) by Jack Souther states that "Canada is commonly thought to occupy a gap in the Pacifc Ring of Fire between the Cascade volcanoes of the western United States and the Aleutian volcanoes of Alaska, yet the Cordillera of BC and Yukon includes more than 100 separate volcanic centers that have been active during the Quaternary." This statement implies that Souther thought that Canada does not in fact occupy any such gap, and thus all Canadian volcanoes are part of the Ring. I would be interested to hear why you feel that they should not be included. Thanks. --Seattle Skier (talk) 03:39, 10 June 2007 (UTC) P.S. I think that some of your edits have been reverted, but please don't take it personally, and please do continue to contribute.

And I have also noticed that you have been changing the Stikine Volcanic Belt to the Northern Cordilleran Volcanic Province (they're the samething). It's better to use the Stikine Volcanic Belt because it has more information, it has a category, and is better in the Volcanic_Arc/Belt section in the infobox. It is also used in the Geological Survey of Canada [1] and here are other links mentioning Canada's volcanoes are part of the Ring of Fire [2] [3]. Hoodoo Mountain is a tuya, not a stratovolcano. Stratovolcanoes are formed mainly by explosive eruptions and contain layers of volcanic ash and lava. Tuyas are a type of distinctive, flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or ice sheet and don't usually have explosive eruptions, which is how Hoodoo Mountain formed. I'm the main one who created most of the Canadian volcano articles (created +100 articles), and still continue making and updating Canadian volcano articles. Again, welcome!
