Eruption of ~1,100 km3 of crystal-rich, high- to low-SiO2 rhyolite Caetano Tuff at 34.0 Ma induced collapse of the Caetano caldera, which was initially ~20 km long ร— 12 to 18 km wide. Major extension beginning in the middle Miocene tilted intracaldera Caetano Tuff into a series of 40ยฐ E-dipping blocks and stretched the caldera to its present day 42-km width.
