Kilauea Caldera Map - Volcano, HI - 'You Are Here' Maps on Waymarking.com

The plaque says, "A volcanic depression is commonly called a crater. A very large crater, like this one at the summit of Kilauea, is called a caldera.

At this point the Kilauea Caldera measures two miles across and 400 feet deep. Geologist believe that the reservoir of hot molten rock that feeds the volcano lies only two miles below.

A caldera forms by the collapse of rocks in the interior of the volcano, the explosion of stocks out of the volcano, and the erosion of the summit by water and wind.

As the decades pass, caldera features change. New lava floes bury old ones. Earthquakes cause sections of the caldera wall to collapse, forming piles of debris called talus. Creates and cracks open on the caldera floor. When and where the next volcanic episode will occur, mo one can be sure."
