I will review this. ceranthor 00:25, 19 July 2018 (UTC)

Lead
"Ampato (possibly from Quechua hamp'atu[1] or from Aymara jamp'atu[2], both meaning "frog") is a dormant 6,288-metre (20,630 ft) stratovolcano in the Andes of southern Peru, about 70–75 kilometres (43–47 mi) northwest of Arequipa." - maybe spread out some of this into two sentences? It's just a lot to digest in the first sentence
"Holocene ash layers in surrounding peat bogs may testify the occurrence of recent eruptions." - missing "to" after "testify"
Done. Jo-Jo Eumerus (talk, contributions) 16:42, 25 July 2018 (UTC)
Geography and geomorphology
"the city of Arequipa lies 70–75 kilometres (43–47 mi) southeast of Ampato.[4]" - instead of repeating the volcano name, maybe just "kilometres... to the southeast"
"some of which have had eruptions in historical time including El Misti, Huaynaputina, Sabancaya and Ubinas." - instead of "have had eruptions", why not "erupted in historical time"
"The edifice is incised by glacial valleys.[10]" - comes abruptly, perhaps move within the section to the last paragraph?
Remedied. Jo-Jo Eumerus (talk, contributions) 16:42, 25 July 2018 (UTC)
Geology
"after the opening of the southern Atlantic Ocean.[8]" - what does opening mean here? why is that important?
"The present day volcanic arc resulted from a narrowing of the Barroso group.[12]" - again, what is the importance of the narrowing? needs more explanation
"but appears to be about on average 0.08–0.09 cubic kilometres per millennium (0.019–0.022 cu mi/ka) but without considering "spurt"-like behaviour; volcano growth in fits and spurts has been observed at many other volcanic arc volcanoes.[16]" - repetition of "but" dilutes the meaning/intent of this sentence
I believe the importance is that this opening causes South America to move westward and increased the rate of subduction. Remedied the others. Jo-Jo Eumerus (talk, contributions) 16:42, 25 July 2018 (UTC)
@Jo-Jo Eumerus: Can you add that to the article? I'll still pass this, but fix that please. ceranthor 17:18, 25 July 2018 (UTC)
Eruptive history
"The southern cone developed in several different stages; a first lavic stage generated lava flows emanating from the summit;[20" - what's a lavic stage? explain
" a first lavic stage generated lava flows emanating from the summit;[20] dating of two lava flows has produced ages of 34,000 ± 8,000 and 40,000 ± 3,000 years before present. More than 20 metres (66 ft) of block-and-ash flows was erupted onto the eastern and western flanks of Ampato,[21] and the block-and-ash flows consist of one andesitic and one dacitic formation; both appear to relate to a lava dome forming stage of volcanic activity. These block-and-ash flows are themselves covered on both the eastern and the western flanks by more thick lava flows, which make up a 150–200 metres (490–660 ft) thick unit and again consist of one andesitic and one dacitic unit; both units appear to have been erupted during the last glacial maximum.[22]" - lots of lava flows and block and ash flows in close vicinity; try finding synonyms or rewording?
"Early Holocene (11,000 - 8,000 years before present) ash layers" - if you're going to explain what Holocene refers to, do it at the first mention, not here
Got these; Holocene is explained here to connect it to the timeline where it is the first mention. Jo-Jo Eumerus (talk, contributions) 16:42, 25 July 2018 (UTC)
Human history
"Ampato was the site of human sacrifice during Inka times" - why Inka rather than Inca?
References
Ref 28 should be decapitalized
Earwig's tool checks out
References seem comprehensive and reliable
Seems to be in good shape. Will pass once these are addressed. ceranthor 14:45, 25 July 2018 (UTC)

​ I think I got all of these. Jo-Jo Eumerus (talk, contributions) 16:42, 25 July 2018 (UTC)
Great! Fix the one issue mentioned above, please. I will pass this assuming that will be addressed. ceranthor 17:18, 25 July 2018 (UTC)
Explained that a little. Jo-Jo Eumerus (talk, contributions) 17:38, 25 July 2018 (UTC)
