A caldera (/ k l d r , k l-/ kawl-DERR-, kal-) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption.When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is lost. Following the 1991 eruption of Mount Pinatubo in the Philippines, cooler than normal temperatures were recorded worldwide and brilliant sunsets and sunrises were attributed to this eruption that sent fine ash and gases high into the stratosphere, forming a large volcanic cloud that drifted around the world.
