Velocity anomalies: An alternative explanation based on data from laboratory experiments Velocity anomalies: An alternative explanation based on data from laboratory experiments
Locations and velocities were calculated for microseisms occurring in samples of rock subjected to triaxial loading and injection of pore fluid. This was accomplished by analyzing arrival times of acoustic emission using an automatic first arrival picker. Apparent velocity anomalies were observed prior to both failure of intact samples and violent slip in samples containing saw cuts...
