Seismic Insights into Earth’s Deep Water Cycle: A Story in Three Parts

The cycling of volatiles like water through Earth’s deep interior plays an important role in plate tectonics and the evolution of our continents and atmosphere. Tracking the path of water throughout this cycle is challenging. Physical samples from deep in the Earth are rare and tell us little about the spatial distribution of volatiles at depth. Seismic imaging can “view” much of the interior of the Earth, but the details of volatile migration are often difficult to separate from other phenomena that affect seismic waves and seismicity. Here we present three examples where seismology can provide insights into the deep Earth volatile cycle, and suggest important future research directions if we are to improve our understanding of this important process.
