1. Among his first programs was a microseismic survey in 1905. 2. Hydraulic fracturing causes induced seismicity called microseismic events or microearthquakes. 3. ESG manufactures and installs microseismic instrumentation and performs microseismic data processing and interpretation services. 4. ESG manufactures and installs microseismic instrumentation and performs microseismic data processing and interpretation services. 5. Microseismic mapping is very similar geophysically to seismology.6. Microseismic noise usually displays two predominant peaks.7. Microseismic events are often used to map the horizontal and vertical extent of the fracturing.8. Since then, ESG has offered complete microseismic monitoring solutions for hydraulic fracture operations throughout the US and Western Canada. 9. Accuracy of microseismic event mapping is dependent on the signal-to-noise ratio and the distribution of sensors. 10. May 9, 1991 : Monitoring of deformation and microseismic activity led to accurate anticipation of this follow up rockslide event.
