Christine A Goulet
Christine Goulet is the Director of the U.S. Geological Survey (USGS) Earthquake Science Center. Her work and research interests are in the field of applied seismology with an aim to improve hazard assessment and positively impact societal resilience.
Dr. Goulet studied Geological Engineering in Canada and obtained her Ms. and Ph.D. degrees in Civil Engineering from UCLA where she developed a graduate course on ground-motion characterization for engineers. She then worked as a consultant for several engineering and seismology projects. She joined the Pacific Earthquake Engineering Research center (PEER) in 2010 where she co-led the NGA-East Program, the largest ground-motion modeling project conducted in the U.S. to date. Joining the Southern California Earthquake Center (SCEC) in 2015, she led the science and integrative activities for large-scale collaborative projects involving diverse disciplines that feed into earthquake hazard and that make extensive use of high-performance computing. Dr. Goulet served on several professional committees and boards, including for the Seismological Society of America and its Eastern Section.

Deterministic physics-based earthquake sequence simulators match empirical ground-motion models and enable extrapolation to data poor regimes: Application to multifault multimechanism ruptures
We use the deterministic earthquake simulator RSQSim to generate complex sequences of ruptures on fault systems used for hazard assessment. We show that the source motions combined with a wave propagation code create surface ground motions that fall within the range of epistemic uncertainties for the Next Generation Attenuation‐West2 set of empirical models. We show the model is well...

U.S. Geological Survey Earthquake Hazards Program decadal science strategy, 2024–33
Executive Summary Earthquakes represent one of our Nation’s most significant and costly natural hazards, with estimated annual loses from earthquakes close to $15 billion in 2023. Over the past two centuries, 37 U.S. States have experienced an earthquake exceeding a magnitude of 5, and 50 percent of States have a significant potential for future damaging shaking; these statistics speak...

Using open-science workflow tools to produce SCEC CyberShake physics-based probabilistic seismic hazard models
The Statewide (formerly Southern) California Earthquake Center (SCEC) conducts multidisciplinary earthquake system science research that aims to develop predictive models of earthquake processes, and to produce accurate seismic hazard information that can improve societal preparedness and resiliency to earthquake hazards. As part of this program, SCEC has developed the CyberShake...

Comparison of nonergodic ground-motion components from CyberShake and NGA-West2 datasets in California
In this study, we compare the Southern California Earthquake Center CyberShake platform against the Next Generation Attenuation‐West2 empirical datasets. Because the CyberShake and empirical datasets cover very different magnitude ranges and site conditions, we develop ground‐motion models (GMMs) for CyberShake datasets to compare trends with empirical GMMs and decompose the residuals...

Toppling of a Trona Pinnacles Spire following the M5.5 RidgecrestaAftershock of June 2020
The 2019 Mw 7.1 Ridgecrest California earthquake rupture passed within 4 km of the Trona Pinnacles, a large group of tufa rock pillars. Reconnaissance following the Ridgecrest mainshock documented fresh damage to several of the Pinnacles. Repeated aerial photogrammetric surveys also documented damage during subsequent aftershocks. Here, we describe the photogrammetric data with emphasis...

Validating predicted site response in sedimentary basins from 3D ground motion simulations
We introduce procedures to validate site response in sedimentary basins as predicted using ground motion simulations. These procedures aim to isolate contributions of site response to computed intensity measures relative to those from seismic source and path effects. In one of the validation procedures, simulated motions are analyzed in the same manner as earthquake recordings to derive...

Selection of random vibration theory procedures for the NGA-East project and ground-motion modeling
Traditional ground-motion models (GMMs) are used to compute pseudo-spectral acceleration (PSA) from future earthquakes and are generally developed by regression of PSA using a physics-based functional form. PSA is a relatively simple metric that correlates well with the response of several engineering systems and is a metric commonly used in engineering evaluations; however...

NGA-East Ground-Motion Characterization model part I: Summary of products and model development
In this article, we present an overview of the research project NGA-East, Next Generation Attenuation for Central and Eastern North America (CENA), and summarize the key methodology and products. The project was tasked with developing a new ground motion characterization (GMC) model for CENA. The final NGA-East GMC model includes a set of 17 median ground motion models (GMMs) for peak...

NGA-East ground-motion characterization model Part II: Implementation and hazard implications
As a companion article to Goulet et al., we describe implementation of the NGA-East ground motion characterization (GMC) model in probabilistic seismic hazard analysis (PSHA) for sites in the Central and Eastern United States (CEUS). We present extensions to the EPRI/DOE/NRC seismic source characterization (SSC) model for the CEUS needed for full implementation of NGA-East. Comparisons...

Toward physics-based nonergodic PSHA: A prototype fully-deterministic seismic hazard model for southern California
We present a nonergodic framework for probabilistic seismic‐hazard analysis (PSHA) that is constructed entirely of deterministic, physical models. The use of deterministic ground‐motion simulations in PSHA calculations is not new (e.g., CyberShake), but prior studies relied on kinematic rupture generators to extend empirical earthquake rupture forecasts. Fully dynamic models, which...

A subset of CyberShake ground-motion time series for response-history analysis
This manuscript describes a subset of CyberShake numerically simulated ground motions that were selected and vetted for use in engineering response-history analyses. Ground motions were selected that have seismological properties and response spectra representative of conditions in the Los Angeles area, based on disaggregation of seismic hazard. Ground motions were selected from millions...

Evaluation of seismic hazard models with fragile geologic features
We provide an overview of a 2019 workshop on the use of fragile geologic features (FGFs) to evaluate seismic hazard models. FGFs have been scarcely utilized in the evaluation of seismic hazard models, despite nearly 30 yr having passed since the first recognition of their potential value. Recently, several studies have begun to focus on the implementation of FGFs in seismic hazard...
