P-WAVE SIGNAL EXTRACTION USING 3-COMPONENT SUBSYSTEM AT TFO
Abstract
Results of an initial analysis of long-period and short-period data collected at the Tonto Forest Seismological Observatory (TFO) are presented in this report. The objective of this work is experimental evaluation of the 3- component systems' capability to reject noise by exploiting the relationship between horizontal and vertical components of the seismic noise field. Short- period data analyzed included three 8-min recordings consisting of two teleseismic signals and one noise sample, while long-period data included one 40-min teleseismic signal (encompassing the P through L interval) and one 40-min noise sample. The long-period data was taken from the 200-km dia extended array with 50-km minimum element spacing, while the short-period data was taken from the 10-km TFO cross-array. Long-period P- and S-waves appeared extremely reproducible across the array, indicating minimal vertical crustal filtering variations.
