Eruption reports

Eruption information has been removed from this page. I’m not a wikipedia expert, but it seems wrong to not at least mention the reports of recent (geologically) activity. Here is a report by Geoexplorers International, Inc, under contract of the US Department of Interior https://pubs.usgs.gov/of/1986/0291/report.pdf

Erlich, E., 1986, Geology of the calderas of Kamchatka and Kurile Islands with comparison to calderas of Japan and the Aleutians, Alaska: U.S. Geological Survey Open-File Report 86-291, ii, 300 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr86291. ~2026-60333-6 (talk) 06:10, 28 January 2026 (UTC)

Not to mention the ~600 AD eruption, Braitseva et al. (1997a,b) ~2026-60333-6 (talk) 06:47, 28 January 2026 (UTC)
