Moment tensors. The colored quadrant indicates compressional motion. the current year is indicated by the color red. |
Orientation of maximum horizontal compressive stress following the convention of Zoback (1992). Red indicates normal faulting, blue thrust faulting and green strike-slip faulting. A combination of colors indicates oblique faulting. |
The classification of the type of faulting is based on the plunge of the P (pressure), T(tension) and B (null axes) as
P/S1-axis B/S2-axis T/S3-axis Regime SH-azimuth
pl > 52 pl < 35 NF azim. of B-axis
40 < pl < 52 pl < 20 NS azim. of T-axis +90
pl < 40 pl > 45 pl < 20 SS azim. of T-axis +90
pl < 20 pl > 45 pl < 40 SS azim. of P-axis
pl < 20 40 < pl < 52 TS azim. of P-axis
pl < 35 pl > 52 TF azim. of P-axis
