Schematic showing collapse processes of Yellowstone Caldera

Detailed Description

Schematic displaying the general processes associated with collapse of Yellowstone Caldera.  (A) Pre-caldera volcanism includes the eruption of dome complexes from the underlying magma chambers.  (B) The caldera-forming eruption evacuates a significant amount of magma from the chamber, causing the overlying crustal block to subside into the void space.  (C) Post-caldera phase displaying the region immediately after the caldera-forming eruption, with the definition of the topographic rim of the caldera and the highly faulted subsided crustal block.  (D) Post-caldera volcanism initiates with the intrusion of magma into the caldera ring faults and faults within the subsided crustal block, producing eruptions of lava flows and dome complexes.
