The Balleny Islands are a series of uninhabited islands in the Southern Ocean extending from 66°15' to 67°35'S and 162°30' to 165°00'E. The group extends for about 160 km (99 mi) in a northwest-southeast direction. The islands are heavily glaciated and of volcanic origin. Glaciers project from their slopes into the sea. The islands were formed by the so-called Balleny hotspot.
Brown Peak is a stratovolcano and the highest point of the Balleny Islands. It is situated on the northern part of Sturge Island.
The Ring of Fire is a region around much of the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur. The Ring of Fire is a horseshoe-shaped belt about 40,000 km (25,000 mi) long and up to about 500 km (310 mi) wide.
Momotombo is a stratovolcano in Nicaragua, not far from the city of León. It stands on the shores of Lago de Managua. An eruption of the volcano in 1610 forced inhabitants of the Spanish city of León to relocate about 48 km (30 mi) west. The ruins of this city are preserved at León Viejo. It also erupted in 1886, 1905, and most recently November 30, 2015.
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified.
Mount Rungwe is a volcanic mountain in Mbeya Region, in Tanzania's Southern Highlands. At an altitude of 2,981 metres (9,780 ft), it is southern Tanzania's second-highest peak. Rungwe's volcano is currently inactive.
Baransky is a stratovolcano located in the central part of Iturup Island, Kuril Islands, Russia.
Yanteles is an isolated stratovolcano composed of five glacier-capped peaks along an 8 km-long NE-trending ridge. It is located approximately 30 km (19 mi) south of the Corcovado volcano in the Chilean X Region within the Corcovado National Park. The name Yanteles can refer only to the main summit, which is also known as Volcán Nevado.
James Healy Seamount is a submarine volcano located among the South Kermadec Ridge Seamounts south of New Zealand's Kermadec Islands. It consists of a volcanic cone that reaches a depth of 1,150 metres (3,770 ft) below sea level, two 2–2.5 kilometres (1.2–1.6 mi) and 1.3 kilometres (0.81 mi) wide calderas and a parasitic cone that reaches a depth of 950 metres (3,120 ft) below sea level. The flanks of the volcano are covered with pumice and volcanic rocks, and hydrothermal venting occurs inside the caldera.
The Brothers Seamount is a Pacific Ocean submarine volcano in the Kermadec Arc, 340 kilometres (210 mi) north east of New Zealand's Whakaari/White Island. It is one of the South Kermadec Ridge Seamounts.
The volcanism of New Zealand has been responsible for many of the country's geographical features, especially in the North Island and the country's outlying islands.
The Smithsonian Institution's Global Volcanism Program (GVP) documents Earth's volcanoes and their eruptive history over the past 10,000 years. The GVP reports on current eruptions from around the world as well as maintaining a database repository on active volcanoes and their eruptions. In this way, a global context for the planet's active volcanism is presented. Smithsonian reporting on current volcanic activity dates back to 1968, with the Center for Short-Lived Phenomena (CSLP). The GVP is housed in the Department of Mineral Sciences, part of the National Museum of Natural History, on the National Mall in Washington, D.C.
The Lavic Lake volcanic field is a volcanic field with extinct cinder cones in the Mojave Desert, in San Bernardino County, California, United States, at 762 m (2,500 ft) elevation. Its cones lie directly alongside historic Route 66 and modern Interstate 40, between Barstow to the west and Ludlow 10 miles to the east.
Monowai Seamount is a volcanic seamount to the north of New Zealand. It is formed by a large caldera and a volcanic cone just south-southeast from the caldera. The volcanic cone rises to depths of up to 100 metres (330 ft) but its depth varies with ongoing volcanic activity, including sector collapses and the growth of lava domes. The seamount and its volcanism were discovered after 1877, but only in 1980 was it named "Monowai" after a research ship of the same name.
Øystein Lund Andersen is a Norwegian photographer and writer.
Macauley Island is a volcanic island in New Zealand's Kermadec Islands, approximately halfway between New Zealand's North Island and Tonga in the southwest Pacific Ocean. It is part of a larger submarine volcano that features a 10.5 by 7 kilometres wide underwater caldera northwest of Macauley Island. Two islets, Haszard Island and Newcome Rock, lie east offshore of Macauley Island. The island is mostly surrounded by high cliffs that make accessing it difficult; the inland parts are mostly gently sloping terrain covered with ferns and grasses.
Curtis Island is an island in the southwest Pacific. It is a volcanic island which, together with neighbouring Cheeseman Island, belongs to the Kermadec Islands, an outlying island group of New Zealand. It is a volcanic island with a fumarolically active crater, while vegetated slopes are nested by seabirds. There are uncertain reports of eruptions and the island has been uplifted by about 18 m (59 ft) during the past 200 years.
