What else can I help you with?
What is the cavity where magma is stored under a volcano called?
This is called the magma chamber.
Reservoir from which volcanic materials erupt?
Magma chamber? Or the lithosphere or a mantle plume, depending on where the volcano is.
A chamber underground containing magma?
A magma chamber.
How big is Krakatoa's magma chamber?
Krakatoa's magma chamber is estimated to be around 40 cubic kilometers in volume. This large magma chamber plays a significant role in fueling the volcanic activity and explosive eruptions of Krakatoa.
A circular depression that forms when a magma chamber empties and causes the ground to sink?
A circular depression that forms when a magma chamber empties is called a caldera. It is a large volcanic crater made from the collapse of a volcano's mouth.

What triggers the small earthquakes the occur around a volcano before an eruption?
Increases in seismic activity around a volcano are typically caused by the movement of magma below the surface into a magma chamber. This causes increases in pressure which leads to fracturing to the rock mass around the magma chamber causing small earthquakes. If the pressure continues to build it would ultimately force the volcano to erupt.
What is crevasse and how does it form?
A crevasse is a deep open crack in a glacier. It is formed when a magma chamber under a glacier causes melting and cracking and causes the glacier to slide into the ocean on the magma
What are hot fluids that can move through small cracks in rock?
Magma and hydrothermal fluids are hot fluids that can move through small cracks in rock. Magma is molten rock beneath the Earth's surface, while hydrothermal fluids are water heated by volcanic activity that can carry minerals and gases. Both can contribute to the formation of igneous rocks and mineral deposits.
Where is the magma in a volcano?
In a magma chamber
A circular depression that forms when a magma chamber empties and causes the ground to sink?
A circular depression that forms when a magma chamber empties is called a caldera. It is a large volcanic crater made from the collapse of a volcano's mouth.
How does the magma chamber work?
Magma Chamber: underground pocket of molten rock
Where is the worlds biggest magma chamber?
The world's largest known magma chamber is located beneath Yellowstone National Park in Wyoming, USA. This massive chamber fuels the park's geothermal activity and is responsible for the park's famous geysers and hot springs.
What causes volcanoes to rupture?
Volcanic eruptions are caused by the buildup of magma (molten rock) beneath the Earth's crust. As pressure builds within the magma chamber, it can lead to fractures in the crust, allowing the magma to escape to the surface in the form of an eruption. Other factors such as the composition of the magma, presence of gases, and tectonic activity can also influence the likelihood and intensity of a volcanic eruption.
