Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
What are the stages of an eruption column?
An eruption column consists of hot volcanic ash emitted during an explosive volcanic eruption. An explosive eruption always begins with some form of blockage in the crater of a volcano When magma flows towards the surface pressure builds, eventually causing the blockage to be blasted out in an explosive eruption. The pressure from the magma and gases are released through the weakest point in the cone, usually the crater. The sudden release of pressure causes the gases in the magma to suddenly froth and create volcanic ash and pumice, which is then ejected through the volcanic vent to create the signature eruption column commonly associated with explosive eruptions.
What kind of eruption has an pyroclastic flow?
An explosive volcanic eruption. Pyroclastic flow is a mixture of fast flowing hot gases that travel down and away from the eruption.
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 is a VEI index?
VEI is the volcanic explosivity index. It rates the severity of explosive volcanic eruptions based on the volume of material ejected and the height of the eruption plume. The scale ranges from VEI 0, indicating a non-explosive eruption, to VEI 8, indicating a super eruption. Each step up the scale represents a tenfold increase in the size of the eruption.
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
Is there a word about volcanoes that begin with a P?
Phreatic Eruption (an explosive volcanic eruption)
What is the largest active volcanic crater?
explosive eruption
Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
What kind of volcanic eruption is Mt Vesuvius?
The eruption of mount Vesuvius was an explosive one.
How are volcanic dust clouds made?
From the explosive reaction of a violent eruption..
What are the 2 types of volcanic eruption?
There are effusive eruptions and explosive eruptions.
Which was the most explosive volcanic eruption of historic time?
tambora, indonesia, 1815
What is the relationship between the silica contents of magma and the explosiveness of a volcanic eruption?
The high the silica content, the explosive and the eruption.

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 kind of eruption has an pyroclastic flow?
An explosive volcanic eruption. Pyroclastic flow is a mixture of fast flowing hot gases that travel down and away from the eruption.
