Talk:Nevado del Ruiz

Apology
A quick apology: a few minutes ago, in attempting to revert an unsubstantiated anon-IP edit, I accidentally re-introduced some vandalism that had already been removed. Sorry. Feline Hymnic (talk) 19:22, 6 October 2009 (UTC)

Cerro Machin
As redacted, the Geography and geology section implies that Machin is an ice-capped volcano, which it isn't. Also the USGS reference doesn't mention it, listing instead El Cisne as one of the 5 volcanoes. Maybe it should list El Cisne instead of Machin, or make it clear that Machin isn't ice-capped. --Canaima (talk) 15:34, 5 September 2011 (UTC)

Comments requested on "Recent activity" subsection

 * 1st paragraph
 * "Between September and October" - meaning, I think, "During September and October..." (There's nothing "between" Sept & Oct)
 * Similarly, from the context I understand "Up to 2011" to mean "From the beginning of 2011..."
 * The sentence beginning: "Also beginning in 2010 were increases..." is awkward on several counts. It appears to jump back, chronologically; it is not clear what else was "beginning in 2010" - why do we need the "also"? We have "correspondent to" which I think should be "corresponding to". It is not clear what peaked in February 2012: increases in sulfur dioxide, or small eruptions of the volcano.
 * 2nd paragraph
 * A comma is advisable after: "After seismicity continued to increase..."
 * "The peak in March passed without a major eruption..." The peak what?
 * It can't be right to say the alert was "raised" to Yellow, when it was  at a higher level
 * Be consistent about "Orange" and "orange"
 * The following clunks a bit: "Over the next few months ash fell frequently until earthquakes increased again in June, and evacuations were ordered by the Emergency Committee of Caldas on news media for 300–1500 people." Some tidier phrasing, and maybe a bit more punc, would help.
 * "indicating an imminent eruption, and an eruption 7.5 kilometers (4.7 mi) in diameter took place" - "eruption ... eruption" should be avoided.

That is all I can see. Hope this helps. Brianboulton (talk) 21:13, 31 March 2013 (UTC)
 * These should all be fixed. Thanks so much!  ceran  thor 21:33, 31 March 2013 (UTC)

Plinian or Vulcanian eruption?
In the article it says that the eruptions are Plinian. Here the Nevado del Ruiz is given as an example for Vulcanian eruptions: https://en.wikipedia.org/wiki/Types_of_volcanic_eruptions#anc Which one is correct? — Preceding unsigned comment added by 193.197.136.53 (talk) 17:45, 9 September 2015 (UTC)

2012 eruption no longer current
I propose we move the 2012 eruption to the "Eruption history" section. Forich (talk) 13:50, 1 April 2023 (UTC)
