Here is a time lapse video of the compass direction of the seismic noise in the Madison Valley of the Yellowstone region from March 4 to April 12 of this year. The seismic noise device was left undisturbed for the entire duration. One second time points were recorded. Noise values greater than 450 mV were excluded to eliminate the signals from the larger discrete local seismic events. The hourly files were concatenated into daily files. Matlab plots of noise direction (in +/- radians from North) vs. 3D noise magnitude were saved as 24 hour .tif files and the freeware Makeavi program was used to create a time lapse video of the 39 days. The center of Lake Yellowstone, under which the region's volcanic hot spot lies, is approximately 70 miles away and at about +2 radians relative to the device. There are clearly periods of increased activity both generally and from this direction lasting for extended times.
