We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Avachinsky — The 1779 eruption was recorded by John Ledyard in his Journal of Captain Cook's Last Voyage, referring to the volcano as 'Paul'. — The journal entry describes 'the mountain Paul' as the one that erupted, but in the context of the entry, 'Paul' refers to Koryak
Cascade Volcanoes — The entry states 'Glacier Peak is the only Cascade Volcano that is made exclusively of dacite.' This is incorrect; Glacier Peak erupts a range of compositions including andesite and dacite, and is not exclusively dacite.
Cascade Volcanoes — The entry says 'the Mount Aix Volcanic Complex, erupted more than 100 km3 of tephra and pyroclastic debris over the span of just three eruptions.' This is not a widely established fact in standard volcanological sources; the Mount Aix complex is not typically
Cerro Sarisariñama — The claim that Sima de la Lluvia was the longest known quartzite cave in the world for about two decades at 1.35 km is inaccurate; it is not widely recognized as such, and its length is not consistently cited as 1.35 km in that context.
Mount Nyiragongo — The claim that the lava lake depth was about 600 m (2,000 ft) prior to the January 1977 eruption is incorrect; the actual depth was approximately 300-400 m.
Mount Nyiragongo — The statement that the 1977 eruption drained the lava lake in less than 30 minutes, killing at least 50 people, is inaccurate; the drainage time is often cited as less than an hour, and the death toll is generally reported as around 70-100 people.
Mount Paektu — The claim that Mount Paektu 'is expected to erupt roughly once every hundred years' is not established canon; there is no widely accepted recurrence interval of exactly 100 years.
Mount Paektu — The specific date '2 January 1997' for the record low of −51°C is not a universally established fact and may be an invented detail.
Mount Pinatubo — The entry states the Tayawan Caldera-forming eruption was five times larger than the 1991 eruption, but the actual volume ratio is about 2.5–3 times larger.
Mount Pinatubo — The LORE section says the volcano rose only about 600 m above nearby plains, but its actual topographic prominence before 1991 was about 1,745 m.
Mount Rainier — The entry states 'Last recorded activity=Between 1820 and 1854', but the widely accepted last recorded eruption or notable activity of Mount Rainier is in 1894, with reports of steam and ash emissions.
Mount Rainier — The entry claims 'a 2025 linguistic analysis identified 20 such names' and repeats this in the DID YOU KNOW section. As of the current date (2025 has not yet occurred), no such analysis can be verified as existing in established canon.
Mount Shasta — The first written record of Mount Shasta is not universally accepted as May 20, 1817, by Narciso Durán; earlier records exist, such as by Juan Bautista de Anza in 1776.
