magma chamber
Underground molten pool
A magma chamber is a large underground reservoir of molten rock beneath a volcano or volcanic region.
Magma accumulates here before eruptions, sometimes pooling for thousands of years.
The chamber's size, depth, and pressure determine eruption intensity: Scientists detected swelling above the magma chamber, suggesting volcanic activity.
