The characteristics of long-period earth noise have been investigated at the 11 high-gain, long-period (HGLP) seismograph stations using as many as three years of analog seismograms and digital data from these stations. The level of earth noise recorded by horizontal component seismographs at HGLP stations, however, is shown to be dependent on local meteorological conditions. This dependency decreases with increasing depth of overburden. The tilt motions recorded by horizontal seismographs are discussed. It is shown that the signal-to-noise ratio on horizontal seismographs can be significantly improved by burial at depth of several hundred meters which removes the major portion of the tilt noise associated with low velocity winds, but the signal-to-noise on the vertical and horizontal seismographs cannot be further improved without going to impractical depths of burial (more than two or three km).
