BOONE, N.C. — While an undergraduate at Appalachian State University, Jake Dorsett ’18 conducted some earthshaking research that was recently published by the Bulletin of the Seismological Society of America.
Dorsett, who is from Monroe, was a double major, earning a B.S. in geology with a concentration in quantitative geoscience and a B.S. in physics with a concentration in applied physics. He also explored geophysics as part of his physics major and is now pursuing a master’s degree in geophysics at Indiana University.
At Appalachian, Dorsett worked with Dr. Scott Marshall, professor in the Department of Geological and Environmental Sciences (GES), along with collaborators at the Universidade de Brasília’s Instituto de Geociências and the University of Massachusetts at Amherst.

Significant historical earthquakes are labeled with stars. Dorsett’s research focused on testing the effects of three proposed connecting faults, shown here as white lines, between the Imperial and San Andreas faults. Photo submitted
The team built a physics-based model that demonstrated the San Andreas Fault in California does not end where most people think — but is, in fact, connected to other faults extending into Mexico.
“To scientists working on probabilistic earthquake forecasting in the Los Angeles area, it is important to consider how the San Andreas interacts with the dozens of other seismically active faults near the boundary,” Dorsett explained.
“When matched with field-based geologists’ observations, our model showed the San Andreas Fault extends approximately 50 miles south of where it was thought to end — which might alter predictions surrounding the next major earthquake,” he continued.
Marshall was Dorsett’s academic adviser at Appalachian. “During an advising meeting, I voiced interest in doing an undergraduate thesis with Dr. Marshall, and we settled on this project,” Dorsett said.
“Dr. Marshall spent a lot of time teaching me the skills required to be a geophysical modeler. He advised me on creating scientific posters, talks and working my thesis into a publication,” he added.
Marshall said, “It is cool that an undergraduate student at Appalachian, through lots of hard work and dedication, can learn to create and analyze cutting-edge computational models that demonstrate something completely fundamental about a fault that has been studied by hundreds of thousands of people.”
Scholarships and support
Dorsett received an Undergraduate Research Assistantship from Appalachian’s Office of Student Research and additional scholarships and travel grants from the GES department.
“Thanks to the financial support, I was able to quit my job as a line cook and have more time to dedicate to scientific research,” Dorsett shared. “I can’t overstate the impact that decision has had on my academic career.”
While Marshall was his primary mentor, Dorsett said he could depend on many of his professors to work with him through difficult concepts, share about their research and guide him in career-oriented decisions.
“The faculty were engaged with students and really wanted us to succeed,” Dorsett said. “They were willing to provide some fantastic opportunities — the type of work that prepared us for graduate school and the industry.”
What’s next for Dorsett? When he finishes his master’s degree, he plans to work in the energy industry as an exploration geologist with Exxon Mobil Corp.
“As long as I get to learn new things every day and continue to solve new and novel problems, I’ll be happy,” he said.
