Comparisons of Surface and Borehole Broadband Ambient Seismic Noise at IRISStation RAR: Raratonga, Cook Islands

摘要

This report addresses reduction of ambient broadband (.01 - 10 Hz) seismic noiseachieved by a 100 m deep borehole deployment on a small oceanic island, Raratonga in the Cook Islands, relative to simultaneously recorded surface levels. Between
