How can they predict a volcano eruption?
By using a tiltmeter to check the ground swelling
How can scientists measure the ground around a volcano before an eruption?
sensors and thermal images
Is this correct pyroclastic flows from composite cone volcanoes are known as calderas?
No. They are simply called pyroclastic flows. A caldera is a depression formed in the ground when a volcano, usually a composite volcano, collapses as the magma chamber partially empties during an especially violent eruption.
What are the weather types before a volcano?
Since a volcanic eruption is a geologic event rather than a weather event, there will be no indication from the weather prior to an eruption. There are, however, geologic indicators that can point to a future eruption. Indicators include earthquakes near the volcano, venting of hot gas, and deformation of the ground.
How does a GPS predict a volcanic eruption?
High-precision GPS can be used to detect shifts in the ground on and near a volcano. This can be used to infer the underground movement of magma, which can help in predicting an eruption.
If you come close to a volcano can you die?
If it an active volcano, yes you can. Lava can be several thousand degrees, and poisonous gasses are given off during an eruption. Sections of ground are unstable and can collapse. During an eruption, it is a VERY unsafe place to be.

Are craters volcanic bombs?
No. A crater is a circular depression in the ground formed by an impact or explosion. A volcano bomb is a blob of lava hurled out during a volcanic eruption.
How can earthquakes be a warning sign that an eruption is about to happen?
The earthquake moves the ground and the movement makes a volcano erupt!
Do the movements in the ground cause the ground to shake?
yes also the faults rub together and make it shake into an earthquake and the eruption of a volcano can start a earthquake.
What hap pends during volcanic eruption?
during a volcanic eruption the plates shift causing the ground to tremble (kinda like an earthquake) causing the tightly packed magma to escape through the top of the volcano. when the magma reaches the top its called lava (but any idiot should already know that:))

What happens to the ground after the volcano has erupted?
nothing just it stays the same
Can earthquakes occur when a volcano erupts?
Yes. In fact, earthquakes and tremors usually precede the eruption of a volcano and are caused by the volcanic activity and pressure building up beneath the ground.
How do you make vlolcanoe erupt?
You can'tmake a volcano erupt.It happens naturally.What happens is, well, first of all, the planet is separated into plates, and when a plate from way below ground or something like that, it goes under into the magma that is in the center of the Earth. Which forces magma to go upward through "escape routes" (volcanoes).When the magma reaches the surface through the volcano it becomes lava, and it comes out the volcano which is an eruption. So you can't make a volcano erupt.
