'''Mount Veniaminof''' ({{langx|ru|Вулкан Вениаминова}}) is an active [[stratovolcano]] on the [[Alaska Peninsula]]. The mountain was named after [[Innocent of Alaska|Ioann (Ivan Popov) Veniaminov]] (1797–1879), a Russian Orthodox missionary priest (and later a prominent bishop in Russia) whose writings on the [[Aleut language]] and ethnology are still standard references. He is a saint of the Orthodox Church, known as Saint Innocent for the monastic name he used in later life.

The volcano was the site of a colossal ([[Volcanic Explosivity Index|VEI]] 6) eruption around 1750 BCE.<ref name=gvp/> This eruption left a large [[caldera]]. In modern times the volcano has had numerous small eruptions (over ten of them since 1930), all at a [[cinder cone]] in the middle of the caldera.

Veniaminof is one of the highest of Alaskan volcanoes. Partly for this reason, it is covered by a [[glacier]] that fills most of the caldera. Because of the glacier and the caldera walls, there is the possibility of a major flood from a future [[jökulhlaup|glacier run]].

The volcano recently began erupting on September 3, 2018, as magma broke through the summit and flowed down its slopes as a lava flow. Despite starting off as an effusive eruption, by November 20, the eruption became more intense and ash was reaching 20,000 feet, prompting the AVO to give a warning for aviation because of the ash posing a threat to aviation. Even an ashfall warning was issued for the nearby town of Perryville.

In 1967, Mount Veniaminof was designated as a National Natural Landmark by the National Park Service.<ref>{{Cite web
