Titila (Russian : Титила) is a shield volcano located in the northern part of Kamchatka Peninsula, Russia. It comprises two shield volcanoes: Titila and Rassoshina, from which Titila is the higher one.
Olympus Mons is a large shield volcano on Mars. The volcano has a height of over 21.9 km as measured by the Mars Orbiter Laser Altimeter (MOLA). Olympus Mons is about two and a half times Mount Everest's height above sea level. It is the largest and highest mountain and volcano of the Solar System, and is associated with the Tharsis Montes, a large volcanic region on Mars.
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica, with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as 15 km (9.3 mi).
These lists cover volcanoes by type and by location.
A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form.
Mount Terror is a large shield volcano that forms the eastern part of Ross Island, Antarctica. It has numerous cinder cones and domes on the flanks of the shield and is mostly under snow and ice. It is the second largest of the four volcanoes which make up Ross Island and is somewhat overshadowed by its neighbour, Mount Erebus, 30 km (19 mi) to the west. Mount Terror was named in 1841 by Sir James Clark Ross for his second ship, HMS Terror. The captain of Terror was Francis Crozier, a close friend of Ross for whom the nearby Cape Crozier is named.
Tolbachik is a volcanic complex on the Kamchatka Peninsula in the far east of Russia. It consists of two volcanoes, Plosky (flat) Tolbachik and Ostry (sharp) Tolbachik, which as the names suggest are respectively a flat-topped shield volcano and a peaked stratovolcano. As Ostry is the mountain's highest point, the entire mountain is often referred to as "Ostry Tolbachik", not to be confused with Ostry, a separate volcano to the north also on the Kamchatka Peninsula.
Mount Shishaldin is a moderately active volcano on Unimak Island in the Aleutian Islands chain of Alaska. It is the highest mountain peak of the Aleutian Islands. The most symmetrical cone-shaped glacier-clad large mountain on Earth, the volcano's topographic contour lines are nearly perfect circles above 6,500 feet (1,981 m). The lower north and south slopes are somewhat steeper than the lower eastern and western slopes. The volcano is the westernmost of three large stratovolcanoes along an east–west line in the eastern half of Unimak Island.
Mount Wrangell, in Ahtna K’ełt’aeni or K’ełedi when erupting, is a massive shield volcano located in Wrangell-St. Elias National Park and Preserve in southeastern Alaska, United States. The shield rises over 12,000 feet (3,700 m) above the Copper River to its southwest. Its volume is over 220 cubic miles (920 km3), making it more than twice as massive as Mount Shasta in California, the largest stratovolcano by volume in the Cascades. It is part of the Wrangell Volcanic Field, which extends for more than 250 kilometers (160 mi) across Southcentral Alaska into the Yukon Territory, and has an eruptive history spanning the time from Pleistocene to Holocene.
Kebeney is an extinct shield volcano located in central Sredinny Range, in the northern part of the Kamchatka Peninsula, Russia. It is a basaltic/andesidic shield volcano with a number of cinder cones on its flanks, aligned along the Sredinny Range NE-SW axis.
Sredinny Range is a mountain range on the Kamchatka Peninsula of Russia. It stretches from northeast to southwest along the center of the peninsula and is made up of volcanoes, mostly shield volcanoes and stratovolcanoes. The highest peak of the range is Ichinsky, a stratovolcano some 3,607 metres (11,834 ft) high. The Sredinny Range is separated from the north–south running coastal Eastern Range (Vostochny) to the east, by the Central Kamchatka Depression.
Ushkovsky is a large volcanic massif located in the central part of the Kamchatka Peninsula, Russia. It is located at the northwestern end of the Klyuchevskaya Sopka volcano group. These volcanoes are also set in a chain linked formation. The highest peak of this massif is Krestovsky. Krestovsky is a stratovolcano, Ushkovsky is a shield volcano.
Yunaska is an uninhabited island which is the largest of the Islands of Four Mountains group in the Aleutian Islands of southwestern Alaska, United States. It has a land area of 66.834 square miles according to the 2000 census.
In volcanology, a pyroclastic shield or ignimbrite shield is an uncommon type of shield volcano. Unlike most shield volcanoes, pyroclastic shields are formed mostly of pyroclastic and highly explosive eruptions rather than relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano. They typically display low-angle flank slopes and often have a central caldera caused by large eruptions. Lava is commonly extruded after explosive activity has ended. The paucity of associated Plinian fall deposits indicates that pyroclastic shields are characterized by low Plinian columns.
Maitland Volcano is a heavily eroded shield volcano in the Northern Interior of British Columbia, Canada. It is 83 km (52 mi) southeast of the small community of Telegraph Creek in what is now the Klappan Range of the northern Skeena Mountains. This multi-vent volcano covered a remarkably large area and was topped by a younger volcanic edifice. Little remains of Maitland Volcano today, limited only to eroded lava flows and distinctive upstanding landforms created when magma hardened within the vents of the volcano.
Pogranichny is a shield volcano in central Kamchatka. It is the highest and the easternmost among three shield volcanoes located north-east of Cherny volcano in the central Sredinny Range.
Yelovsky is an extinct shield volcano in central Kamchatka. The volcano is the edifice among several overlapping small basaltic shield volcanoes. Yelovsky is located at the east of the crest of the Sredinny Range.
Tamu Massif is an extinct submarine shield volcano in the northwest Pacific Ocean, with the characteristics of a hybrid between a mid-ocean ridge and a shield volcano. On 5 September 2013, researchers announced that it could be a single volcano, a claim which, if corroborated, would make Tamu Massif the largest known volcano on Earth. Tamu Massif is located in the Shatsky Rise about 1,600 km (990 mi) east of Japan. The volcano covers an area of about 553,000 square kilometres (214,000 sq mi). Its summit is about 1,980 m (6,500 ft) below the surface of the ocean, and its base extends to about 6.4 km (4.0 mi) deep. The volcano is about 4,460 metres (14,620 ft) tall.
