Which is the most destructive a strombolian or a plinian?
Plinian eruptions are the most destructive. Strombolian eruptions are usually fairly small.
These volcanic eruption types is the least violent?
Which of these volcanic eruption types is the least violent? B. Hawaiian A. Pelean B. Hawaiian C. Strombolian D. Plinian
Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
Which of these substances is usually not present in explosive volcanic eruptions?
Pahoehoe is one substance usually not present in explosive volcanic eruptions. Tephra, lava and other gasses are typically present during an eruption.
What types of lava will most likely lead to a volcanic eruption of an effusive nature?
Shield volcanoes have effusive eruptions. Effusive eruptions are a volcanic phenomenon; in some ways the opposite of explosive eruptions. An effusive eruption is characterized by an outpouring of low viscosity lava which has a fairly low volatile content. Usually, shield volcanoes have effusive eruptions.

What types of eruption does a shield volcano have?
Shield volcanoes usually produce effusive eruptions.
These volcanic eruption types is the least violent?

Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
What kind of of volcanic eruption occurs when basaltic magma is present?
Basaltic magma usually produces a Hawaiian or Stombolian style of eruption.

Pahoehoe is one substance usually not present in explosive volcanic eruptions. Tephra, lava and other gasses are typically present during an eruption.

Can scientists predict volcanic eruptions?
Yes, scientists can predict volcanic eruptions, but only to a certain extent of accuracy. One method is to use earthquakes. Earthquakes usually increase and become more violent before a volcanic eruption
Do volcanic eruptions cause earthquakes?
Not usually. Although earthquakes often occur before a volcanic eruption, they are not the cause. The earthquakes are the result of magma (molten rock) moving underground leading up to an eruption. A few volcanic eruptions are thought to have been triggered or initiated by earthquakes, but this is not the typical case.
Can non explosive volcanoes have pyroclastic flows?
The answer is Explosive . It is explosive because during a explosive eruption there are clouds of ash, gas , and rock , and with a pyroclastic flow there is dust and ash . there for the answer must be explosive .
What eruption is worse mafic or silicic?
Eruptions involcing silicic or felsic magma are generally the worst. Eruptions of mafic material are usually effusive or only mildly explosive, producing cinders or lava flows. Eruptions of felsic material often produce large ash clouds and deadly pyroclastic flows.
Why do composite volcanoes usually produce violent eruptions?
As the magma approches the surface, has gate trapped below, and pressure builds up. Once the pressure is to great to be contained, there is a violent eruption
