Fiber-optic sensing of our dynamic Earth

The Atterholt Group at the University of Arizona turns telecommunication fibers into ultra-dense seismic arrays. This yields coverage every few meters over tens to hundreds of kilometers, providing resolution conventional seismic networks cannot. We combine these datasets with techniques from applied mathematics to answer a host of questions. We get high-resolution images of fault zones, Moho variability, and subducting slabs. We track earthquake rupture propagation in fine detail. We measure how basins, volcanoes, and precipitation shape geohazards.
