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.
