... these conditions are created during hydraulic stimulation. Depending on the stress regime, dip-slip events can be explained by slip on horizontal fault planes in strike-slip environments and by slip on vertical fault planes in normal faulting domains. Due to local rotations of the stress field, these fault...

..., and the relationship between microseismicity and hydraulic / natural fractures. We show that stress inversion with event focal mechanisms could help us better interpret microseismicity by identifying slip direction, and the true fault plane on which it occurs.
