The proposed methodology is composed of data preconditioning, global path tracing, and final addition to compute the total travel time. We...

... of the microseismic event using peak amplitudes and traveltimes of P and S waves as input features. To examine the factors affecting the results of moment tensor inversion using ML model, we analyze the sensitivity of three factors, the error in the peak amplitude due to noise, the error in travel time due to picking...
