Closer monitoring of hydrogeochemical changes in the Cascade volcanic arc has been in effect since 2009 to track recent volcanic unrest. This study analyzes data collected from several sites across this region from 2009 to 2016 using a program called MATLAB to create spectrograms using Fourier analysis to find anomalies or correlations from previous Cascade studies. Results showed consistent diurnal and yearly signals, but did not clearly follow any trends. The findings in this study add to the support of using Fourier analysis along with baselines for hydrogeochemical data to compare future volcanic, earthquake, and tectonic events.
