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
Examples of cinder cone volcanoes are Kula and Karapinar in Turkey; Taal Volcano in the Philippines; Hverfjall in Iceland; El Jorullo, Parícutin and Pinacate Peaks in Mexico; Mounts Leura, Fox and Elephant in Australia; Royal Society Volcano in Antarctica; Manda-Inakir on the Ethiopia-Djibouti border and Barren Island in the Andaman Islands. The United States hosts over 100 cinder cones, mainly in western states and Hawaii.Full Answer >
In spite of some heavily destructive properties, volcanoes play an important role in the environment. According to Oregon State University, volcanoes create new islands and land, provide habitats for pioneer species, create economic mineral deposits and generate beautiful landscapes.Full Answer >
Many volcanoes erupt without an explosion. These volcanoes are called nonexplosive volcanoes because the lava flows fluidly from the mountain rather than exploding into the air with rocks and ash.Full Answer >
Although volcanoes are commonly known for their destruction, they also play some useful roles. On the negative side, volcanoes destroy houses and cities, displace populations, disrupt business, generate tsunamis and destroy habitats and crops. On the positive side, volcanoes create new islands and land, generate tourism attraction points, create beautiful landscapes and scenery and provide habitats to pioneer species, notes Volcano World.Full Answer >
