Want this question answered?
No. Many volcanoes are dormant or inactive.
in some ways yes in other its no
the inactive wolcanoes are Antibia : Laguna 2. Bangcay : Nueva ecija 3. Batulao : Batangas 4. Carakay : Biliran 5. Homahan : Sorsogon 6. Dagatan : quezon 7. Bagua : Cagayan 8. Diogo island : Batanes 9. Alligator : Laguna 10Juban : Sorsogon
With some exceptions, volcanoes are generally not dangerous to people. Your chance of being killed by a volcano is 1 in 80000 over your lifetime, which is far less than your chance of being killed in say a motor vehicle accident (1 in 67). There are also two classifications for inactive volcano's. Volcanoes which have not erupted for a significant amount of time are known as dormant volcanoes. Volcanoes which have not erupted in human history are known as extinct volcanoes. Extinct volcanoes are never expected to erupt again, and are therefore not dangerous unless they have been misclassified. So no, I do not think that all volcanoes whether active or inactive are dangerous. The only dangerous volcanoes are dormant volcanoes that explode suddenly with little or no warning.
The term used to refer to an inactive volcano is "dormant".The other term to call an inactive volcano is "extinct volcano". But as the years pass by some of the extinct volcanoes may become active depending on the earth's core condition.
unless you have some kinda of amazing superpowers or a giant rock you will not be able to stop the activty of a volcano
Volcanoes can be active or inactive. When a volcano is active there is magma or lava moving around getting ready to make an explosion. When a volcano is inactive there is either rocks and bits of other stuff melting in the main vent making magma getting ready to become active or they are not doing anything, just sitting there like a mountain. The four main types of volcanoes are shield volcanoes, composite volcanoes, also called stratovolcanoes, cinder cones, and lava domes. Composite volcanoes are the most abundant, and an example is Mount Fuji in Japan. These volcanoes are formed from layers of ash. In contrast, shield volcanoes are gently sloping volcanic mountains built almost fully of lava flows. They were named on account of their shape , which is reminiscent of an ancient warrior's shield. These volcanoes are typically much larger then composite volcanoes. Lava domes and Cinder cones are much smaller than shield or composite volcanoes.Thats what some of the Volcanoes are!
Some of the volvanoes of Hawaii are Haleakala, Mauna Kea, and Diamond Head (all inactive) Kilauea (has been erupting for years now) and Mauna Loa (dormant)
Some active volcanoes in Philippines are Mayon, Bulusan, Smith, Canlaon, Ragaing, Hibuk-Hibok, Didcas, Calayo, Banahaw, Pinatubo, Cagua, Iriga, Biliran, Parker, Matutum, Bud Dajo, and Makaturing.
there is a side vent and main vent on most volcanoes. some just have a main vent
Volcanoes are large formations that having an opening where gases and lava can escape out of the Earth's magma chamber. Some types of volcanoes are shield volcanoes, super volcanoes, and mud volcanoes. The largest volcano based on height is Tamu Massif.
It is important to know the ways volcanoes are predicted and how far the lava will reach
