What is the area where magma collects inside a volcano before an eruption?
The area where magma collects inside a volcano before an eruption is called the magma chamber. This is a reservoir beneath the volcano where molten rock accumulates and builds up pressure, eventually leading to an eruption.
What sign can scientists study to try to predict volcanic eruptions?
Before an eruption, magma moves into the area beneath the volcano and collects in a magma chamber, or reservoir. As it comes closer to the surface, the magma releases gases. These events can offer valuable clues about the likelihood of an eruption.
Is magma a explosive eruption and why?
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.
How long does magma have to heat up to erupt?
The time it takes for magma to heat up before an eruption can vary significantly depending on several factors, including the type of magma, the geological setting, and the conditions within the magma chamber. In some cases, magma can accumulate and heat over thousands to millions of years before erupting. In other scenarios, changes in pressure, temperature, or the influx of new magma can trigger an eruption after just a few days to weeks. Ultimately, predicting the exact timing of an eruption is complex and depends on the specific dynamics of each volcanic system.
Before magma erupts it collects under a volcano in a?
Magma chamber. This is a large underground reservoir that holds the molten rock before it is forced to the surface during an eruption. The size and depth of the magma chamber can vary depending on the volcano.
What comes out first magma or lava?
magma is lava that has not been exposed to the air before eruption.
How does magma chamber differ from a vent?
A Magma Chamber is a space (that can change size) at a depth below a volcano in which magma can accumulate prior to an eruption. A volcanic vent is a conduit connecting the magma chamber to the surface. It is though this that the magma flows during an eruption.
What causes small earthquakes before a volcanic eruption?
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
Is molten rock called lava before it erupts?
No, it is called magma before eruption and lava afterwards.
What is the area where magma collects inside a volcano before an eruption?
The area where magma collects inside a volcano before an eruption is called the magma chamber. This is a reservoir beneath the volcano where molten rock accumulates and builds up pressure, eventually leading to an eruption.
What about magma affects how explosive an eruption will be?
The composition of the magma affects how explosive a volcanic eruption will be.
How is strength of a volcano eruption related to the magma in the volcano?
If the magma is more viscous, the eruption is stronger.
Were there any earthquakes before the eyjafjallajokull eruption?
Yes, there were several earthquakes leading up to the Eyjafjallajökull eruption in 2010. These earthquakes were caused by the movement of magma beneath the volcano, which eventually led to the eruption.
Is a caldera another name for a magma chamber?
No. A magma chamber is the area under a volcano where molten rock is stored. A caldera is a depression in the ground formed during an exceptionally violent volcanic eruption. A caldera forms when a volcano drains a large volume of magma from the magma chamber, causing the volcano to collapse into the space left behind.
Is magma a explosive eruption and why?
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.

How can the composition of magma affect the way volcano erupts?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
