Temporal Attributes of the Ambient Seismo-Acoustic Environment: La Junta, Colorado

Abstract

During the period 9 to 29 October 1986, seismic and atmospheric pressure data were recorded at the AFGL operated array at La Junta, Colorado. The purpose of this effort was to develop statistical models of the noise environments at this site for use in defining event detection capabilities of the array. Analysis of these data demonstrates that peak noise amplitudes for 1- second windows could adequately be modeled as Type II Gumbel extreme value distributions, EXII (u,k). Further, it was shown that there is at best only weak correlation between the noise fields in both a broad-and narrow-band sense. Keywords: Seismic noise; Seismo-acoustics; Pressure noise; La Junta.
