Examples of dead volcanoes, more commonly referred to as extinct volcanoes, include Mount Ashitaka in Japan, Hohentwiel in Germany, Huascarán in Peru, Kyushu-Palau Ridge in the Philippine Sea, Mount Buninyong in Australia, Shiprock in the United States and Zuidwal in the Netherlands. Geologists define an extinct volcano as one that has not erupted in 10,000 years and no longer has an underground supply of lava.Know More
Additional volcanoes that geologists believe are extinct include Kilimanjaro in Tanzania, Mount Warning in Australia, Chaîne des Puys in France and Elbrus in Russia. Some volcanoes listed as dormant may actually be extinct, while other volcanoes technically listed as extinct may just be dormant. For example, the 2004 eruption of Alaska's Fourpeaked Mountain occurred more than 10,000 years after its previous eruption, meaning that its classification as extinct was incorrect.
Other famous examples of extinct volcanoes erupting after more than 10,000 years include the Soufriere Hills volcano in Montserrat in 1995 and the Pompeii-destroying eruption of Mount Vesuvius in 79 A.D. Although geologists believe that the Yellowstone Caldera in Yellowstone National Park has not erupted for over 640,000 years, some scientists believe it may still be active, due to evidence of minor lava flow and frequent small earthquakes, which are a sign of seismic activity.Learn more about Volcanoes
Landforms created by lava include shield volcanoes, stratovolcanoes or composite volcanoes, lava domes and flood basalts, according to Tulane University. Although primarily caused by lava, stratovolcanoes also contain volcanic material such as ash. Cinder cones also contain significant amounts of ash.Full Answer >
Cinder cone volcanoes generally spew lava dramatically when they erupt, though the eruptions are not particularly dangerous to human populations. Dramatic and beautiful as the eruptions may be, they are quite insignificant in comparison to the eruptions of other types of volcanoes.Full Answer >
Famous composite volcanoes include Mount Fuji in Japan, Mount Cotopaxi in Ecuador, Mount Shasta and Mount Lassen in California, Mount Hood in Oregon, Mount St. Helens and Mount Rainier in Washington, Mount Pinatubo in the Philippines, and Mount Etna in Italy. Many of these volcanoes are located around the Pacific Rim.Full Answer >
There are more than 550 active volcanoes in the world, almost all of which are located at convergent tectonic plate boundaries. This includes all of the volcanoes in the Pacific Ring of Fire, such as Japan's Mount Fuji, as well as Mount Saint Helens, Popocafepetl in Mexico and Azul in the Andes Range.Full Answer >
