Magma storage refers to the process by which molten rock, or magma, is contained within the Earth's crust before it erupts as a volcanic eruption. This area of research focuses on understanding the mechanisms and dynamics of magma storage, including how magma is stored, transported, and pressurized within the crust. Scientists study various features such as magma chambers, dikes, and sills to better understand how magma behaves and evolves before volcanic eruptions occur. Understanding magma storage is crucial for predicting volcanic activity and mitigating potential hazards associated with volcanic eruptions.
