In 1989 the Voyager 2 spacecraft observed ice volcanoes (cryovolcanism) on Triton, a moon of Neptune and in 2005 the Cassini-Huygens probe photographed fountains of frozen particles erupting from Saturn´s moon Enceladus.
Some volcanoes consist of a crater alone, with scarcely any mountain at all; but in the majority of cases the crater is situated on top of a mountain (the volcano), which can tower to an enormous height.
Volcanoes that terminate in a principal crater are usually of a conical form.

A volcano is a geological landform (usually a mountain) where magma (rock of the Earth's interior made molten or liquid by high temperature along with a reduction in pressure and/or the introduction of water or other volatiles) erupts through the surface of the planet.
Stratovolcanoes or composite volcanoes such as Mt. Fuji in Japan, Vesuvius in Italy, Mount Erebus in Antarctica, and Mount Rainier in the northwestern United States are tall conical mountains composed of both lava flows and ejected material.
Volcanoes may be either dormant (having no activity) or active (near constant expulsion and occasional eruptions), and change state unpredictably.

There is no exact definition for a super volcano, but the term is often used to refer to volcanos that have produced exceptionally large eruptions in the past.
A super volcano differs from a regular volcano in that there is often no mountain peak associated with it.
As fascinating as the history of Yellowstone volcano is, however, most professional geologists who study the site are not concerned that the park is on the brink of a catastrophic eruption.

To address this airborne hazard, the Alaska Volcano Observatory (AVO)—a joint operation of the U.S. Geological Survey (USGS), the Geophysical Institute of the University of Alaska-Fairbanks, and the Alaska State Division of Geological and Geophysical Surveys—installed six seismic stations near Pavlof in July 1996.
The new instruments, designed to complement satellite images and other observations of the volcano, were installed with funding from the Federal Aviation Administration because of the volcano's frequent eruptions and their potential impact on air travel.
The summit of the volcano remains bare as new lava flows and spatter melt the new snowfall.

 Munching Mauna Loa - Creatures of the Deep Feast on the 1877 Kealakekua Bay Submarine Lava Flows
The Volcano Watch of December 19, 2002 detailed an oceanographic cruise studying the 1877 submarine eruption of Mauna Loa in Kealakekua Bay.
Local residents told the steamer's crew that the violent submarine eruption from one of Mauna Loa's radial vents was accompanied by a strong earthquake felt in the nearby settlements of Ke`ei and Ka`awaloa, along with 1-m (3-ft) wide ground cracks that split inland nearly 5 km (3 miles) from the eruption site.
Rapidly rising gasses ejected from the undersea volcano decreased the water's density and hence its ability to support the heavy ship, causing it to slip beneath the waves.
