Dodgy picture caption edit

"1822 artist rendition of the eruption of Vesuvius, depicting what the AD 79 eruption may have looked like."

This is an 1822 artist rendition of an eruption at that time. What is the basis for the assertion that the AD 79 eruption may have looked like? Is this conjectured similarity, a perception of the 1822 artist or the person who captioned the photo here ?Eregli bob (talk) 12:45, 24 February 2010 (UTC)Reply

Pliny the Younger wrote the description of the 79AD eruption which as an example of objective impersonal observation still serves the scientific community as the way to observe and report. Scrope - the artist would have almost certainly read that description and probably seen other similar eruptions.The Geologist (talk) 14:42, 22 August 2013 (UTC)Reply


The Pinatubo article says Pinatubo's 1991 eruption was Plinian. 69.118.29.171 (talk) 04:23, 18 April 2010 (UTC)Reply

Correct - it was a full blown Plinian eruption.The Geologist (talk) 14:36, 22 August 2013 (UTC)Reply

Section for Sub-Plinian (VEI 3-4) edit

There are many references in Google Books to "sub-Plinian" (also "subplinian"). Also mentioned in VEI#Classification 3-4. I would think a section here, possibly after before or after "Ultra-Plinian", might be in order? Cheers, Facts707 (talk) 07:08, 7 May 2017 (UTC)Reply

Krakatau edit

The 1883 eruption of Krakatau is listed as an example in both this article and the phreatic eruption article, which is somewhat confusing. From the summary of one of the refs used in the phreatic article, it looks as if a phreatic eruption occurred only as a precursor to the main eruption, though this isn't clear. Any other explanations? PaleCloudedWhite (talk) 20:41, 17 March 2018 (UTC)Reply

Added Mount St. Helens back edit

Described by multiple sources as a Plinian eruption. It has been removed as a sector collapse - it may need to be explained in the article why these are mutually exclusive if it is removed again. — Preceding unsigned comment added by 65.188.193.250 (talk) 01:29, 14 July 2018 (UTC)Reply

I think this section is trying to give examples so the reader knows what a plinian eruption is. I agree that eventually the eruption became plinian. However, the notable thing about Mt St Helens was the lateral blast and therefore I don't think it is suitable for use as an example of a plinian eruption. Op47 (talk) 17:28, 1 August 2018 (UTC)Reply
