Examples of volcanoes found along divergent plate boundaries include Krafla Volcano in Iceland, as well as Erta Ale and Oldoinyo Lengai in Africa. The process of volcanic formation along divergent boundaries is called spreading center volcanism.Continue Reading
Plate boundaries are classified according to the type of plate movement that occurs in these areas. Divergent plate boundaries are regions where two adjacent plates move apart. The most prominent divergent boundaries are the Mid-Atlantic Ridge and the East African Rift Zone.
Krafla Volcano is situated in the northern section of Iceland, a volcanic country that traverses the Mid-Atlantic Ridge. Erta Ale and Oldoinyo Lengai are located within the East African Rift Zone. These volcanoes are created due to rifting, where faults along the surface continue to widen and spread out. The magma that rises to fill the cracks erupt, which results to volcanic formation.Learn more about Volcanoes
Volcanic arcs are formed when an oceanic plate is forced under a continental plate and the water-soaked crust melts as it's forced below the ocean floor, creating magma that feeds volcanoes on the continental side of the subduction zone. Stratovolcanoes are created in an arc around the subduction zone. The geologic phenomenon occurs all around the world but is most commonly seen around the Pacific Ocean tectonic plate in a formation known as the ring of fire.Full Answer >
Examples of volcanic eruptions during the 21st century include the eruption of Iceland's Hekla volcano in 2000, North Sumatra's Mount Sinabung in 2014 and Japan's Mount Ontake in 2014. Other eruptions include the Tungurahua volcano in Banos, Ecuador, in 2014 and Mount Merapi in Indonesia in 2010.Full Answer >
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 >
Three major events take place at plate boundaries: the formation of volcanoes and mountains, and a greater occurrence of earthquakes. There are also three main types of plate boundaries: divergent, convergent and transform.Full Answer >
