Figure 3.6: (A) Distribution of detected microseismic events during 2006-2007 surrounding 7400 Level. Colour scaling represents location error with warm colours indicating increased error. The 400 Orebody is located within the excavation and is outlined in Figure 2.5. The skew of production-related events reflects the position of events relative to microseismic network. Events having a high error are further removed from the network; (B) Distribution of macroseismic events surrounding 7400 Level. 50
Figure 3.7: Detected seismicity corresponding to levels 7200, 7400 and 7530 respectively. Events have been filtered by location error (< 30 ft.) and by depth and are restricted 50 feet above and below the level. Colour scaling represents moment magnitudes between M= -1.5 and M= 0.5. 51
