As with geometries, the location and scale of the events can be transformed to allow for multiple coordinate systems. The model can be viewed in two or three dimensions (Figure 2...

... ABSTRACT ABSTRACT: Full-waveform signals of mine-induced seismic events recorded in a hard-rock mine were processed in order to study attenuation effects, source parameters and scaling laws for such events. Attenuation along the source-sensor path had a significant effect on the recorded...
