When the magma gets close to the surface, the gases dissolved in it start to come out, forming gases which help the magma rise further and erupt. If there is a lot of gas in the magma, it may explode as the gases expand. There may also be triggers like a landslide that uncaps the magma reservoir (like at Mt. St. Helens in 1980) or an interaction with groundwater that causes an explosion.
Before a volcano erupts, there are typically signs of increased seismic activity such as earthquakes, deformation of the volcano's surface, and gas emissions. This is often preceded by a build-up of magma beneath the surface, which creates pressure that eventually results in an eruption. Monitoring these signs allows scientists to issue warnings and evacuate nearby areas to prevent loss of life.
They first give off warning signs.
---------
The magma moves into this place that is called (here at least) a waiting chamber. Here, it gives off gasses, volcanos also cause quick earthquakes or vibrations.
Magma gathering in a chamber causes slight swelling of the volcano's slopes. Gases released near the volcano can be measured for changes or in quantity.
Hope you got all that ^_^

What happens when a volcano erupts from the cone?
Idk im kinda dumb......... Stuff just happens ok? So leave me alone poopface
A volcano which no longer erupts is called a?
deader than a door nail!!! It's dormant or inactive.
What do you see before a volcano erupts?
Before a volcano erupts, there are usually signs such as increased seismic activity, swelling of the volcano due to magma rising, and the release of gases like sulfur dioxide. These signs help scientists and authorities monitor and predict volcanic activity to issue warnings and evacuate areas at risk.
When a volcanoe is no longer erupts what is it called?
I am fairly certain that when a volcano no longer erupts, it is now called a dormant volcano. I think that is all that it is called
What do you call a volcano when it no longer erupts?
Distinct
What happens as a volcano erupts?
destruction
What happens if a volcano never erupts?
dormant
What happens to the people after a volcano erupts?
THEY die of course!
Can you predict when a volcano erupts?
precdiction about the story before
What happens as magma from beneath the earths surface erupts as a volcano?
which are the following?
Where to go if a volcano erupts?
Type your answer here... were do you go when a volcano erupts
What hapens before a volcano erupts?
Eruptions are usually preceded by earthquakes
What sign did the volcano give before it erupts?
they give warnings to tell them that its about to erupt
What causes the earthquakes at the base of a volcano shortly before it erupts?
Tectonic plates.
What are you doing before volcano erupts?
Before a volcano erupts, people are just living their lives, going about their daily routines. There typically wasn't much warning before a major eruption, and there still isn't a good early detection and warning system.
What is the last thing that happens in the life of volcano?
It goes over many hot spots and it no longer erupts
What is a volcano that erupts sometimes called?
An Active Volcano.
