Long-Term Broad-Band Vertical Earth Noise Structure at Very Long Period Experiment Sites

Abstract

A series of one-hour samples of seismic noise have been taken from vertical instrument channel recordings at the Very Long Period Experiment (VLPE) sites for evaluation of the long-term broad-band earth noise field in the VLPE network. Converted power spectral density estimates of the root-mean-square noise amplitudes in the samples were corrected for channel response characteristics and then examined for long term trends and both broad and narrow band variability. Correlation of intraband noise variability is discussed.
