The Mono Lake volcanic field east of Yosemite National Park and north of the Mono Craters in central eastern California is a series of cinder cones in Mono Lake and on its shore. It is one of the most recently active volcanoes in California, the last eruptions having occurred at Paoha Island only 100 or 230 years ago. Paoha Island's eruption was the appearance of a so-called cryptodome - a shallow intrusion of a viscous rhyolitic magma body that uplifted the lake bottom sediments.
Intraplate volcanism: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
Volcanic Ash Advisory Centres: Much current eruption news is provided by the 9 Volcanic Ash Advisory Centres (VAAC) distributed around the globe. The VAACs provide a vital service for aviation safety.
