Description
strikeSlip = slip*cos(rake); dipSlip = slip*sin(rake); horizontalAcrossStrike = dipSlip*cos(dip); verticalDown = dipSlip*sin(dip).
Geological orientations and component projections require explicit axis, angle and sign conventions. A straight segment or planar-set correction is a geometric model, not an independently measured structure or hazard assessment.
strikeSlip = slip*cos(rake); dipSlip = slip*sin(rake); horizontalAcrossStrike = dipSlip*cos(dip); verticalDown = dipSlip*sin(dip).
When to use this tool
Use Fault Displacement Component Projection Term when checking one supplied geological orientation or displacement projection.
How to use the tool and how it works
- Enter slip, rakeRadians, dipRadians. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read strikeSlip, dipSlip, horizontalAcrossStrike, verticalDown. Use the output convention below.
Require nonnegative slip and dipRadians in [0,pi/2]. strikeSlip = slip*cos(rake); dipSlip = slip*sin(rake); horizontalAcrossStrike = dipSlip*cos(dip); verticalDown = dipSlip*sin(dip).1

}Limitations and assumptions
- Rake and dip use radians on the stated local fault coordinates. Components are signed under that convention; no global azimuth, fault geometry estimation or hazard assessment is performed.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified observations, reference directions and full geometry before interpreting real structures or practical stability.
