Yellowstone Seismic Noise Is A Composite Of Many Discrete Events

A project log for Device for Seismic Noise Analysis

A device that monitors the statistics of the magnitude and the 3-D direction of seismic noise might detect earthquakes before they happen.

Plots of the moving average of the seismic noise probability data seem to show that the noise comes in discrete clusters of abnormal statistics. The following plot is a 10 second moving average of the 1 second combined noise probability data points. Click or double click on the image to see more detail.

Here is the compass direction of 24 hours of noise 3D magnitude in +/- degrees from North.  East is to the left. North is 0 degrees and South is either + or - 180 degrees.  Much of the noise originates from the West, with a strong concentration along the North/South axis. The device is roughly 70 miles Northwest of the center of Yellowstone lake.
