Chelsea Scott is an assistant research scientist with the School of Earth and Space Exploration at Arizona State University. Scott integrates remote sensing and field-based observations of earthquake activity over different timescales to understand how tectonic forces drive seismic activity and surface processes shape the Earth's landscape. Scott's research focuses on the following questions:
Surface rupturing strike-slip earthquakes: How can the on-fault and near-field surface deformation be best measured with geodesy?
What are the transient and permanent landscape changes following a decadal scale rain storm in the the Atacama Desert of Northern Chile?
Do ancient tectono-geomorphic markers in the Atacama Desert record the strain field produced by great earthquakes on the South America- Nazca subduction zone?
Do great subduction zone earthquakes trigger backarc earthquakes?
What is the uncertainty in fault geometry parameters due to atmospheric noise in InSAR data?

Much of my research at ASU has focused on understanding how the Earth’s shallow crust accommodates plate motion during earthquakes and along aseismic faults. This research contributes to fundamental knowledge about earthquake physics, bridges observations over the decadal to millennial timescale, and informs seismic hazard. I developed new observational techniques to measure the far-field and largely elastic deformation as well as the on-fault and permanent deformation. For the 2016 Magnitude 7 Kumamoto, Japan, earthquake, I developed new insights about the mechanical behavior of faults and produced the first distributed coseismic slip inversion using differential topography data (Scott et al., 2019; Scott et al., 2018). Along the Creeping Section of the Central San Andreas Fault in California, I produced the spatially most dense set of 3D creep rate measurements and showed that the fault location has shifted over time (Scott et al., 2020A; Scott et al., 2020B). I have been highly involved in cyber-infrastructure research with OpenTopography and led the development of on-demand differencing tools (Scott et al., 2021) and the state-wide topographic differencing activity (Scott et al., 2022A). I spent a month as a visiting scientist at the University of Nice, France, and this collaboration led to a publication on measuring the geometry of normal faults in Eastern California (Scott et al., 2022B). In collaboration with a large team of students, professors, and industry geologists, I am leading and managing the ASU work to understand the seismic risk posed by fault displacement to critical infrastructure.
