Answer to Question 1

This caldera formed about 7000 years ago when a composite cone, named Mount Mazama, violently extruded 50 to 70 cubic kilometers of pyroclastic material. With the loss of support, 1500 meters of the summit of this once prominent cone collapsed, producing a caldera that eventually filled with rainwater.

Answer to Question 2

Yellowstone-type calderas.
