| Title: | How Calderas Form. |
| Caption: | This animation traces a process very similar to that which formed Crater Lake in the Oregon Cascade Range. It shows an eruption partially emptying a magma chamber, leading to the collapse of the composite volcano and the creation of a caldera, which subsequently holds a lake. |
