SALT LAKE CITY — Shaking from a future Utah earthquake could be amplified by sediment thickness, according to a new University of Utah study.

Researchers installed an “extensive network” of seismic probes across the valley. Many were put in place in the month following the 2020 Magna earthquake, when there were plenty of aftershocks to be monitored.

According to Fan-Chi Lin, an associate professor of geology and geophysics and the study’s leader, researchers set out to understand the area’s sedimentary structure.

“One of the biggest questions we had was why our observations didn’t agree with previous studies,” Lin said.

Currently, scientists rely heavily on the Wasatch Front community velocity model to predict future seismic behavior. Although it’s a useful tool, limited sampling and i
