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.

Fumarole — The claim that fumaroles release 'no liquid or solid material' is inaccurate; fumaroles can occasionally emit small amounts of liquid or fine solid particles.
Fumarole — The temperature range 'About 100 to 1,000 °C (210 to 1,800 °F)' is too high; typical fumarole temperatures rarely exceed 800 °C.
Maar — The entry states the size range of maars as '20 to 3,000 m across; 5 to 200 m deep', but the largest known maars (Espenberg) are up to 8 km diameter and 300 m depth, so the stated maximum diameter of 3,000 m is factually incorrect.
Pyroclastic flow — Pyroclastic density currents have not been observed on the moon; the claim that they can be observed on the moon is not supported by established volcanology canon.
Stratovolcano — The claim that 'over 700 stratovolcanoes have erupted lava during the Holocene' is not an established canonical figure; the Smithsonian Global Volcanism Program lists over 1,300 volcanoes of all types, and the specific number of stratovolcanoes is not precisel
Stratovolcano — The claim that 'extensive flows of this lava are rare, but they can travel up to 8 kilometers' is inaccurate because documented andesitic or dacitic lava flows from stratovolcanoes have reached 10–15 km, making 8 km an incorrect maximum.
Submarine volcano — The statement 'Below about 2,200 meters depth, water becomes a supercritical fluid and cannot boil' is factually imprecise because the critical point of seawater is at about 407 °C and 29.9 MPa, corresponding to a depth of roughly 2,990 meters, not 2,200 meter
Volcanic arc — The entry states 'The shape of a volcanic arc is usually convex toward the subducting plate', but in standard volcanology, volcanic arcs are typically convex toward the overriding plate (i.e., concave toward the subducting plate).
Volcanic arc — The entry says 'Prominent arcs such as the Kuril Islands, the Aleutian Islands, and the Sunda Arc have a radius of about 20 to 22 degrees.' This is incorrect; the radius of curvature for these arcs varies and is not a fixed 20–22 degrees for all, e.g., the Ale
Volcanic cone — The entry states that cinder cones have a common height range of 'over 800 meters', but widely-known volcanology canon indicates that cinder cones typically range from about 30 to 400 meters in height, with very rare exceptions; 800 meters is far above the est
Volcanic cone — The entry states that tuff cones have rim-to-rim diameters of 300–5,000 meters, but established canon gives typical diameters for tuff cones as ranging from about 1,000 to 2,000 meters; 5,000 meters is excessively large and more characteristic of tuff rings or
Volcanic island — The typical size range '1 to 104 square kilometers' is incorrect; volcanic islands can be much larger or smaller, with no established canon limiting them to this range.
Volcanic island — The claim that 'low islands such as Banaba, Henderson Island, Makatea, Nauru, and Niue rise over 50 metres above sea level' is partially incorrect because Henderson Island's highest point is about 33 meters, which does not exceed 50 meters.
