Kilauea Volcano - 10:52am

This is a list of lists of active and extinct volcanoes sorted by country. There are separate lists of Antarctic, submarine, and extraterrestrial volcanoes.

A list of volcanoes in United States of America and its territories.

A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface.

Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth's crust in the interiors of plates, e.g., in the East African Rift, the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis" volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core-mantle boundary, 3,000 km deep in the Earth.

Kīlauea ( /kiːlaʊˈeɪ.ə/; Hawaiian: [ˈkiːlɔuˈwɛjə]) is a volcano in the Hawaiian Islands, and one of five shield volcanoes that together form the island of Hawaiʻi. Kīlauea means "spewing" or "much spreading" in the Hawaiian language, referring to its frequent outpouring of lava. The Puʻu ʻŌʻō cone has been continuously erupting in the eastern rift-zone since 1983, making it the longest rift-zone eruption of the last 200 years. Thirty-five eruptions have taken place since 1952, not including the current episode. Lava less than 1000 years old covers 90% of Kīlauea, and the volume of erupted material is large enough to pave a road around the world three times.

This is a list of UNESCO World Heritage Sites in the Americas (North America, Central America, South America, and the Caribbean). Hawaii and Easter Island are included here given their political ties to the Americas despite being geographically located in Oceania. On the other hand, Greenland has been included here as part of North America despite of its cultural and political associations with Europe. Mexico leads the Americas hosting 31 sites, and is ranked the fourth in the world.

A UNESCO World Heritage Site is a place (such as a forest, mountain, lake, desert, monument, building, complex, or city) that is listed by the UNESCO as of special cultural or physical significance. The list is maintained by the international World Heritage Programme administered by the UNESCO World Heritage Committee, composed of 21 states parties which are elected by their General Assembly.

The program catalogues, names, and conserves sites of outstanding cultural or natural importance to the common heritage of humanity. Under certain conditions, listed sites can obtain funds from the World Heritage Fund. The programme was founded with the Convention Concerning the Protection of World Cultural and Natural Heritage, which was adopted by the General Conference of UNESCO on November 16, 1972. Since then, 186 states party have ratified the convention.

As of 2011^[update], 936 sites are listed: 725 cultural, 183 natural, and 28 mixed properties, in 153 States Parties. Italy is home to the greatest number of World Heritage Sites to date with 47 sites inscribed on the list. UNESCO references each World Heritage Site with an identification number; but new inscriptions often include previous sites now listed as part of larger descriptions. As a result, the identification numbers exceed 1200 even though there are fewer on the list.

Hawaiʻi Volcanoes National Park, established in 1916, is a United States National Park located in the U.S. State of Hawaiʻi on the island of Hawaiʻi. It encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive volcano. The park gives scientists insight into the birth of the Hawaiian Islands and ongoing studies into the processes of vulcanism. For visitors, the park offers dramatic volcanic landscapes as well as glimpses of rare flora and fauna.

In recognition of its outstanding natural values, Hawaiʻi Volcanoes National Park was designated as an International Biosphere Reserve in 1980 and a World Heritage Site in 1987. In 2000 the name was changed by the Hawaiian National Park Language Correction Act of 2000 observing the Hawaiian spelling.

The Americas, or America, are lands in the Western hemisphere, also known as the New World.

In the English language, the Americas refers to the landmasses of North America and South America with their associated islands and regions, while America refers almost exclusively to the United States of America.

The Americas cover 8.3% of the Earth's total surface area (28.4% of its land area) and contain about 13.5% of the human population (about 900 million people).

The United States of America (also called the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west, across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity).

North America (Spanish: América del Norte or Norteamérica; French: Amérique du Nord; Dutch: Noord-Amerika; Papiamento: Nort Amerika; Kalaallisut: Amerika Avannarleq) is a continent wholly within the Northern Hemisphere and almost wholly within the Western Hemisphere. It is also considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America, and to the west and south by the Pacific Ocean.

North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 4.8% of the planet's surface or about 16.5% of its land area. As of July 2008, its population was estimated at nearly 529 million people. It is the third-largest continent in area, following Asia and Africa, and the fourth in population after Asia, Africa, and Europe.

Puʻu ʻŌʻō (often written Puu Oo, and pronounced [ˈpuʔu ˈʔoːʔoː], roughly "poo-oo oh-oh") is a cinder/spatter cone in the eastern rift zone of the Kīlauea volcano of the Hawaiian Islands. Puʻu ʻŌʻō has been erupting continuously since January 3, 1983, making it the longest-lived rift-zone eruption of the last two centuries.

Although the name is often translated as "Hill of the ʻŌʻō Bird" from Hawaiian, there is a different explanation of the Hawaiian appellation. The word ʻŌʻō also means digging stick. Because in Hawaiian legends the volcano goddess Pele uses her magic rod pāoa to create volcanic pits, this seems to be the intention for the naming. The cone was originally informally called "Puʻu O" by volcanologists, who simply assigned letters to vents as they arose during the first part of the eruption.

By January 2005, 2.7 cubic kilometers (0.65 cu mi) of magma covered an area of more than 117 square kilometers (45 sq mi) and added 230 acres (0.93 km²) of land to the Southeast coast of Hawaiʻi. So far, the eruption has claimed 189 buildings and 14 kilometers (8.7 mi) of highways, as well as a church, a store, the Wahaʻula Visitor Center, and many ancient Hawaiian sites, including the Wahaʻula heiau. The coastal highway has been closed since 1987, as it has been buried under lava up to 35 meters (115 ft) thick.
