<span class="mw-page-title-main">Mount Katmai</span> Stratovolcano in Katmai National Park, Alaska, USA

Mount Katmai is a large active stratovolcano on the Alaska Peninsula in southern Alaska, located within Katmai National Park and Preserve. It is about 6.3 miles (10 km) in diameter with a central lake-filled caldera about two by three miles in size, formed during the Novarupta eruption of 1912. The caldera rim reaches a maximum elevation of 6,716 feet (2,047 m). In 1975 the surface of the crater lake was at an elevation of about 4,220 feet (1,286 m), and the estimated elevation of the caldera floor is about 3,400 ft (1,040 m). The mountain is located in Kodiak Island Borough, very close to its border with Lake and Peninsula Borough. The volcano has caused ten known fatalities due to gas exposure.

<span class="mw-page-title-main">Mount Spurr</span> Volcanoin the state of Alaska

Mount Spurr (Dena'ina: K'idazq'eni) is a stratovolcano in the Aleutian Arc of Alaska, named after United States Geological Survey geologist and explorer Josiah Edward Spurr, who led an expedition to the area in 1898. The Alaska Volcano Observatory (AVO) currently rates Mount Spurr as Level of Concern Color Code Green. The mountain is known aboriginally by the Dena'ina Athabascan name K'idazq'eni, literally 'that which is burning inside'.

<span class="mw-page-title-main">Mount Pavlof</span> Active volcano in Alaska, United States

Mount Pavlof or Pavlof Volcano is a stratovolcano of the Aleutian Range on the Alaska Peninsula. It has been one of the most active volcanoes in the United States since 1980, with eruptions recorded in 1980, 1981, 1983, 1986–1988, 1996–1997, 2007, 2013, twice in 2014, 2016, and is currently erupting as of August 2021. Basaltic andesite with SiO2 around 53% is the most common lava type. The volcano is monitored by the Alaska Volcano Observatory- a joint program of the United States Geological Survey (USGS), the Geophysical Institute of the University of Alaska Fairbanks (UAFGI), and the State of Alaska Division of Geological and Geophysical Surveys (ADGGS). With a threat score of 95, the threat from future eruptions is considered to be high; much of this threat comes from the possibility of disruption of nearby air routes by large releases of ash. The mountain currently has basic real-time monitoring, but the USGS would like to improve instrumentation at the site. The mountain shares a name with the nearby Pavlof Sister, which last erupted in 1786.

<span class="mw-page-title-main">Bogoslof Island</span> Volcanic island in the U.S. state of Alaska

Bogoslof Island or Agasagook Island is the summit of a submarine stratovolcano at the south edge of the Bering Sea, 35 miles (56 km) northwest of Unalaska Island of the Aleutian Islands chain. It has a land area of 319.3 acres (1.292 km2) and is uninhabited. It is 1,040 meters (3,410 ft) long and 1,512 m (4,961 ft) wide, with a peak elevation of 490 feet (150 m). The stratovolcano rises about 6,000 ft (1,800 m) from the seabed, but the summit is the only part that projects above sea level. The island is believed to be relatively new, with the volcano being entirely below sea level before 1796, and most of the presently 300-acre island being formed by eruptions since 1900.

<span class="mw-page-title-main">Mount Cleveland (Alaska)</span> Nearly symmetrical stratovolcano on Chuginadak island

Mount Cleveland is a nearly symmetrical stratovolcano on the western end of Chuginadak Island, which is part of the Islands of Four Mountains just west of Umnak Island in the Fox Islands of the Aleutian Islands of Alaska. Mt. Cleveland is 5,675 ft (1,730 m) high, and one of the most active of the 75 or more volcanoes in the larger Aleutian Arc. Aleutian natives named the island after their fire goddess, Chuginadak, who they believed inhabited the volcano. In 1894 a team from the United States Coast and Geodetic Survey visited the island and gave Mount Cleveland its current name, after then-president Grover Cleveland.

<span class="mw-page-title-main">Frosty Peak Volcano</span> Volcano in Alaska, United States

Frosty Peak Volcano, also known as Mt. Frosty, Frosty Volcano, or Cold Bay Volcano, is a 6,299 ft (1,920 m) stratovolcano at the southwest end of the Alaska Peninsula in the U.S. state of Alaska.

<span class="mw-page-title-main">Korovin Volcano</span> Volcano in the U.S. state of Alaska

Korovin Volcano is one of four volcanic centers of the Atka Volcanic Complex, located near the town of Atka on the northeast part of Atka Island in the Aleutian Islands chain, Alaska, United States. At 5,030 feet (1,530 m), Korovin is the highest point on the island.

<span class="mw-page-title-main">Lava lake</span> Molten lava contained in a volcanic crater

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.
