Understanding resurgence and restlessness at calderas: insights from climatic vs post-climatic eruptive compositions with particular reference to Toba, Sumatra

Creator:

Bowers, Jade M., de Silva, Shanaka L., and Mucek, Adonara E.

Abstract:

Although calderas and the caldera cycle are well studied, the relationship between caldera-forming eruptions and post-caldera volcanism is poorly understood. The chemical characteristics of the erupted products suggest that two end member compositions are involved during resurgence: (1) remnant magma of similar composition to the magma of the climactic eruption;...
