This article has been rated as Mid-importance on the project's importance scale.
This article is written in British English, which has its own spelling conventions (colour, travelled, centre, realise, defence, artefact), and some terms that are used in it may be different or absent from other varieties of English. According to the relevant style guide, this should not be changed without broad consensus.
As it currently stands, this article is almost entirely plagiarized from its first source (the Smithsonian Global Volcanism Program). I don't have the knowledge to fix this, but it should probably be addressed! SkyBlueWater (talk) —Preceding undated comment added 21:24, 15 November 2017 (UTC)
