Automatic event detection and picking of P-wave arrivals
Kimberly Anne Munro
We have presented a procedure for detecting a microseismic event and locating the arrival time of the first P-wave. This algorithm was investigated using synthetic data and data from Turtle Mountain, Alberta. The method worked very well in locating the synthetic event; detecting it at the exact time in which it was situated. However, when faced with a microseismic event recorded by 6 receivers on Turtle Mountain, the algorithm only detected half of the channels to within 5 ms of the manual pickings, while the other half were detected to within 20 ms.
