... be attributed to the influence of noise in the inversion process. The mechanisms are primarily dip-slip/horizontal-slip (DSHS) style sources with a consistent polarity, however, there are notable exceptions where the mechanism polarity is reversed. The existence of mechanism polarity reversals is shown...

... Abstract Microseismicity induced by hydraulic stimulation is known to exhibit peculiar source mechanisms patterns -namely, dip-slip or strike-slip events with polarity reversal, regardless of the background stress. Such events typically strike parallel to the maximum horizontal stress, which...
