Agency / Branch: DOD / USAF
Contract: N/A
Award Amount: $49,630.00
 

Abstract:

THIS WORK WILL EXAMINE THE FEASIBILITY OF RECORDING MICROEARTHQUAKES AND MICROTREMOR NOISE AT HIGH FREQUENCIES (UP TO 50 HZ), ANALYZING THE FOURIER AND RESPONSE SPECTRUM CHARACTER AT HIGH FREQUENCIES TO DETERMINE NEAR SURFACE ROCK ATTENUATION, AND RELATING THIS TO ENGINEERING ROCK PROPERTIES. TWO SITES WILL BE INSTRUMENTED IN CALIFORNIA (A HARDAND SOFT-ROCK SITE) WHERE AVAILABLE WELL DATA INDICATE ROCK PROPERTIES TO DEPTHS OF 0.6 AND 1.8 KM, RESPECTIVELY. MICROSEISMS WILL BE RECORDED AT THESE TWO SITES AND WILL BE ANALYZED TO EVALUATE HIGH FREQUENCY CHARACTERISTICS AND TO CALCULATE INTRINSIC ATTENUATION. THE INFERRED ENGINEERING PROPERTIES OF THE ROCK WILL BE COMPARED TO BOREHOLE DATA TO EVALUATE THE FEASIBILITY OF THE METHOD AS A SCREENING TOOL FOR SITE CHARACTERIZATION.
