Mission Overview

Over one hundred years after the devastating Great Earthquake, our expedition explored the NSAF, the history of past earthquakes, and the intertwined relationships between large earthquakes and biologic diversity along this, the fastest moving fault in western North America. Our multidisciplinary exploration helped us to understand how tectonic history relates to biodiversity hotspots, and to be able to predict the response these biologically active areas have to future disturbances.
