Modeling Ground Motion at University of Nevada, Reno

During my undergradute career I was hired by the Nevada Seismological Laboratory to run computer simulations of ground motion in the Las Vegas Valley. This reasearch resulted in a paper that resulted in a peer reviewed publication the Bullitien of Seismological Society of America (BSSA). Some key figures from the publication are shown below and a copy of the publication can be found here.

A) Bandpass-filtered observed recorded (thin black traces) and ShakeZoning 3-d synthetic velocity seismograms (thick gray traces) from the nearest station to the source.  B) Frequency spectra of the NSZ synthetic (gray) and observed (black) seismograms from the Little Skull Mountain scenario.
