Short summary
In order to assess the influence of deformational processes within accretionary prisms, we track the evolution of the energy budget. We track the consumption of energy stored in internal deformation of the host rock, energy expended in frictional slip, energy used in uplift against gravity and total energy input. We find that the energy used in internal deformation is < 1% of the total and that the energy expended in frictional slip is the largest portion of the budget.
