I am a Geologist with the Earthquake Hazards Program and was recently on detail with the Office of Communications and Publishing as a Public Affairs Specialist.
I started at the USGS as a Support Geologist with the Earthquake Hazards Program (EHP) in December, 2019 where I help my team conduct research of active faults (primarily) in the Intermountain West via fieldwork, mapping and other desktop / GIS research methods and by maintaining field equipment and vehicles. Within this position I have contributed to projects related to the Eastern Tennessee Seismic Zone, the Wasatch fault zone, updates to the National Seismic Hazard Model, and more.
I manage USGS social media accounts and help with EHP, GHSC (Geologic Hazards Science Center), and general USGS science outreach, education, and communication by creating social media content, through local community outreach, with interactive ArcGIS storymaps (aka Geonarratives - see "Maps" below) and more.
From March-December 2021 I worked as a detailee with the Office of Communications and Publishing where I helped cover and communicate a variety of science happening within the USGS via media engagement, writing news releases and social media content, and more (see "News", below).
Science and good science communication to implement positive change and awareness are what I'm most passionate about. I love working at the USGS and connecting people to the important science we do.

Simplifying complex fault data for systems-level analysis: Earthquake geology inputs for U.S. NSHM 2023
As part of the U.S. National Seismic Hazard Model (NSHM) update planned for 2023, two databases were prepared to more completely represent Quaternary-active faulting across the western United States: the NSHM23 fault sections database (FSD) and earthquake geology database (EQGeoDB). In prior iterations of NSHM, fault sections were included only if a field-measurement-derived slip rate was estimateNon-USGS Publications**

Plotting multiple fault representations: Applications for National Seismic Hazard Model 2023 update (NSHM-faultmaps)
The National Seismic Hazard Model (NSHM) utilizes a fault sections database (FSD) throughout the model workflow. Working towards a 2023 NSHM release, the NSHM23 FSD encompasses a major update with the addition of new fault sections, as well as the revision of existing fault sections from prior FSD (2014). The additions and revisions were largely based on the U.S. Geological Survey's Quaternary FauCompilation of geologic slip rate constraints used in 1996-2014 U.S. National Seismic Hazard Models (ver. 2.0, February 2022)
A key input for probabilistic seismic hazard analysis (PSHA) is geologic slip rate data. Here, we compile all geologic slip rates that are reportedly used in U.S. National Seismic Hazard Map (NSHM) releases from 1996, 2002, 2007, 2008, and 2014. Although a new NSHM was released in 2018, no changes were made in geologic slip rate data used. The geologic slip rates are collated from existing NSHM reEarthquake geology inputs for the U.S. National Seismic Hazard Model (NSHM) 2023 (western US) (ver. 2.0, February 2022)

A key input for probabilistic seismic hazard analysis (PSHA) is geologic slip rate data. Yet, no single database exists to house all geologic slip rate data used in these calculations.

Surface Rupture Map of the 2020 M 6.5 Monte Cristo Range earthquake, Esmeralda and Mineral counties, Nevada
The 15 May 2020, M6.5 Monte Cristo Range earthquake was the largest earthquake in Nevada in over 66 years and occurred in a sparsely populated area of western Nevada about 74 km southeast of the town of Hawthorne. The earthquake produced surface rupture distributed across a 28-km-long zone along the eastward projection of the Candelaria fault in the Mina deflection of the central Walker Lane. Post - Web Tools
