Abstract

Seismic attenuation is a fundamental property of rocks and is defined as the inverse of quality factor (1/Q, where Q is the quality factor). Due to lack of reliable data, attenuation is very poorly understood. Most of the published attenuation measurements are done in megahertz frequency range and thus are not applicable to low frequency seismic waves. To address this issue, a low frequency, low-amplitude apparatus was built to measure seismic velocities and attenuation
