Shown here are seismograms of some of the more recent earthquakes and other seismic activity
recorded at Huntsville, Alabama on home-built instruments including a Shackleford-Gundersen
horizontal seismometer, and an Inyo force-balance broadband vertical seismometer designed by
Dave Nelson and Brett Nordgren. These instruments are connected to a computer data system
hosting the WinSDR datalogger and Winquake data analysis software developed by Larry Cochrane.
