Surface Microseismic System
•Six surface seismic stations were installed on Turtle Mountain in 2003/2004
•Measurements of small seismic events are used to diagnose changes in the structure of the mountain caused by rock movement
An arrange of six surface passive microseismic stations were installed on the east side of the mountain as shown.  The aim of this array was to detect and source located microseismic events within the array that my be due to slope movements or continued collapse of the underground coal workings (abandoned).  These stations were installed in winter 2003/2004 and to this point have not provided reliable results due to a variety of issues, including sensor frequency and assumptions on the rock mass characteristics (and associated velocity models).
