    This Seismometer is no toy!

    Sure! There was a microseismic event near Knoxville in the early morning hours of Jan 30. The first picture is the USGS seismometer reading (about 7 miles from my device) and the second picture is the device output. The green line is the vector magnitude of the seismic noise and the blue line is the noise statistics. The third graph is a polar plot of vector magnitude on compass direction, where 0 = North.
