Active volcano



An active volcano is a volcano that has erupted during the Holocene (the current geologic epoch that began approximately 11,700 years ago), is currently erupting, or has the potential to erupt in the future. A volcano that is not currently erupting but could erupt in the future is known as a dormant volcano. Volcanoes that will not erupt again are known as extinct volcanoes.

Overview
There are 1,350 potentially active volcanoes around the world, 500 of which have erupted in historical time. Many active volcanoes are located along the Pacific Rim, also known as the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes.

Historical time (or recorded history) is another timeframe for active. The span of recorded history differs from region to region. In China and the Mediterranean, it reaches back nearly 3,000 years, but in the Pacific Northwest of the United States and Canada, it reaches back less than 300 years, and in Hawaii and New Zealand it is only around 200 years. The incomplete Catalogue of the Active Volcanoes of the World, published in parts between 1951 and 1975 by the International Association of Volcanology, uses this definition, by which there are more than 500 active volcanoes. , the Smithsonian Global Volcanism Program recognizes 560 volcanoes with confirmed historical eruptions.

Countries with the most Holocene volcanoes, according to the Smithsonian Institution National Museum of Natural History Global Volcanism Program:


 * 1) United States: 165
 * 2) Japan: 122
 * 3) Russia: 117
 * 4) Indonesia 117
 * 5) Chile: 91

Countries with the most volcanoes active since 1960:


 * 1) Indonesia: 55
 * 2) Japan: 40
 * US: 39 (mostly volcanic areas in and around Hawaii, Alaska, and Pacific territories)
 * 1) Russia: 27
 * 2) Chile: 19
 * 3) Papua New Guinea: 13
 * 4) Ecuador: 12

As of 2013, the following are considered Earth's most active volcanoes:
 * Kīlauea, the famous Hawaiian volcano, was in nearly continuous, effusive eruption (in which lava steadily flows onto the ground) between 1983 through 2018, and had the longest-observed lava lake.
 * Mount Etna and nearby Stromboli, two Mediterranean volcanoes.
 * Piton de la Fournaise, in Réunion, erupts frequently enough to be a tourist attraction.

, the longest ongoing (but not necessarily continuous) volcanic eruptive phases are:
 * Mount Yasur, 111 years
 * Mount Etna, 110 years
 * Stromboli, 108 years
 * Santa María, 101 years
 * Sangay, 94 years

Other highly active volcanoes include:


 * Mauna Loa in Hawaii is the largest active volcano in the world. Its summit is more than 4 km above sea level, and 17 km above its base in the sea floor.
 * Mount Nyiragongo and its neighbor, Nyamuragira, are Africa's most active volcanoes.Lava Lake Nyiragongo 2.jpg's lava lake]]
 * Erta Ale, in the Afar Triangle, has maintained a lava lake since at least 1906.
 * Mount Erebus, in Antarctica, has maintained a lava lake since at least 1972.
 * Mount Merapi
 * Whakaari / White Island, has been in a continuous state of releasing volcanic gas since before European observation in 1769.
 * Ol Doinyo Lengai
 * Ambrym
 * Arenal Volcano
 * Pacaya
 * Klyuchevskaya Sopka
 * Sheveluch

Holocene volcanoes with large populations within 5 km:

Michoacan-Guanajuato volcano in Mexico and Tatun Volcanic Group in Taiwan both have more than 5 million people living within 5 km of the volcano. Campi Flegrei in Italy and Ilopango in El Salvador both have populations of over 2 million people living within 5 km of the volcanoes. Hainan Volcanic Field in China, San Pablo Volcanic Field in the Philippines, Ghegham Volcanic Ridge in Armenia, Dieng Volcanic Complex, in Indonesia, and Auckland Volcanic Field in New Zealand all have over 1 million people living within 5 km of each volcano.
