What are the volcanic type eruptions least to greatest?
Volcanic eruptions can be categorized from least to greatest intensity as follows: Hawaiian eruptions are typically gentle, characterized by flowing lava. Next, Strombolian eruptions involve sporadic bursts of lava and gas. Following that are Vulcanian eruptions, which are more explosive, ejecting ash and larger volcanic rocks. Finally, Plinian eruptions are the most violent, producing massive columns of ash and pyroclastic flows.
What type of volcano is Mt Toba?
Mt. Toba is a supervolcano, which is a type of volcano capable of producing massive eruptions with a Volcanic Explosivity Index (VEI) of 8, the highest level. These types of eruptions are thousands of times more powerful than typical volcanic eruptions.
Only plinian and pelean volcanic eruptions features what flow?
Pelean volcanic eruptions feature pyroclastic flows, which are fast-moving currents of hot gas, ash, and volcanic rock fragments. Plinian eruptions also produce pyroclastic flows, but they are characterized by massive vertical columns of ash and gas rising high into the atmosphere.
What do only the most violent volcanic eruptions feature?
The most violent volcanic eruptions are found in destructive/convergent plate boundaries. 80% of the world's active volcanoes are found occur along destructive boundaries. Acid-lava and composite volcanoes also cause the most violent eruptions as the lava is viscous and the opening of the volcano is sometimes blocked by hardened lava, causing a huge massive explosion during the eruption.
Which of these volcanic eruption types is the most violent Plinian Hawaiian Fissure Strombolian?
The most violent type of volcanic eruption among those listed is the Plinian eruption. Plinian eruptions are characterized by high eruption columns, massive ash plumes, and volcanic explosivity index values of 4 or 5. These eruptions are named after Pliny the Younger, who described the eruption of Mount Vesuvius in 79 AD.
What element could start an ice age?
Massive Volcanic Eruptions hence ...Ice Age
What is the most dectructive type of wave?
In terms of natural disasters, tsunamis are among the most destructive waves. They are caused by underwater earthquakes, volcanic eruptions, or landslides and can result in widespread destruction when they make landfall. Tsunamis can cause massive flooding and loss of life.

What is a volcano explosive index?
Volcanic explosive index is a measure of how explosive a volcanic eruption is based largely on the amount of material released. It ranges from VEI-0 for non explosive eruptions to VEI-8 for massive super eruptions.
What causes masive climate changes?
global warming, massive (vei8) volcanic eruptions & meterorite hits (ask the dinosaurs)
What type of volcano is Mt Toba?
Mt. Toba is a supervolcano, which is a type of volcano capable of producing massive eruptions with a Volcanic Explosivity Index (VEI) of 8, the highest level. These types of eruptions are thousands of times more powerful than typical volcanic eruptions.
What are massive slabs of rock which move on the earth's surface colliding with one another and generating earthquakes and volcanic eruptions?
Tectonic Plates
What event appear to separated succeeding geological period?
There are often very large meteor impact events and/or extended series of massive volcanic eruptions.

Is volcano a natural disaster?
Volcanic eruptions are natural disasters because they release massive amounts of matter and energy in a very short time. If this occurs near human population centers it is possible for there to be so much damage the event would be called a disaster. Because humans are unable to have any control over volcanos erupting and because these events would happen even if humans were not on earth they are natural disasters.
