Project Abstract

Volcanoes are outputs to a hidden transport network of magma in the Earth's crust. We hope to use the NAVDAT geologic dataset from volcanoes around the Western US to constrain the topology and dynamics of this network. These data include approximate ages and location of eruptions (best constrained in the last 5.2 Million years - the Pliocene Epoch), along with compositional data that may be used to infer timescales and processes within the network. This project includes statistical analysis of data, network inference, and forward dynamic modeling.
