... lineations to be clearly defined through machine learning approaches. By using the moment tensors in this area, and combining that with nearest-neighbor clustering, the spatial variations in the orientations of the stress tensor are defined. Comparing the stress orientations with the high-precision locations...

... that the faster S 1 -wave is along the radial direction at about an azimuth of E12.7 o S, while the slower S 2 -wave is in the tangential direction perpendicular to that of S 1 -wave. This radial direction is consistent with major-semi axis orientation of induced micro-earthquake distribution. The averaged S-wave...

... We present a semi-automated workflow to statistically evaluate relationships between faults and production. First, we estimate 3D faults and fault orientations using a 3D-CNN. Next, we apply fast marching for a shortest path calculation to faults. This creates a 3D volume of distances with each...
