Landscapes developed in actively deforming regions are often simulated and interpreted through the lens of long-term mean or effective rates of rock uplift, but in reality, rock uplift in these settings reflect contributions from both slow interseismic fault slip and fast coseismic earthquake deformation. The extent to which the stochastic nature of rock uplift is reflected in long-term topography, or whether all of the short-term variability "averages out" over geologically relevant time periods, remains an open question. Exploring that question is the focus of my CAREER grant funded by the National Science Foundation.

Developing Methods to Simulate Earthquakes and Associated Processes in Landscape Evolution Models
The SPAT Lab is in the process of building a series of components for Landlab that allow the simulation of surface deformation resultant from earthquakes. In detail, this contains a series of components for building arbitrary fault geometries, either dipping or vertical faults, a component for generating synthetic earthquake catalogs for events occurring on a fault created by the fault component, and a component for identifying areas likely to produce coseismic landslides. Both interseismic fault slip and individual earthquake ruptures are simulated as elastic dislocation. In preparation for the release of these components, we are prepping a manuscript that documents the internal logic of the components and presents examples of their use. Stay tuned!
