Abstract
A six-station microseismic monitoring array at Turtle Mountain in southern Alberta detected numerous microseisms during the observation period from 1986 to 1996. In this paper, we select a subset of the recorded events, those with clear P and S arrivals and detected by more than three stations for hypocenter-location analysis. Hypocenters are located using a computer program named HYPOMH, which employs a Bayesian algorithm. The error distribution of the hypocenters is also determined by the program. Results of the analysis indicate a concentration of hypocenters at the summit and eastern slope of the mountain. Furthermore, several swarms of events are located with foci ranging from 1 to 1.5 km below the surface of the Frank Slide debris. Few microseisms coincide with the distribution of the remaining (un-collapsed) mine works.
