RMS Velocity Dix Equation Interval Velocity Calculator
Dix equation interval velocity between two horizons from RMS velocities and zero-offset times.
Description
Dix equation interval velocity between two horizons from RMS velocities and zero-offset times.
RMS Velocity Dix Equation Interval Velocity Calculator is a focused tool for the following task. Dix equation interval velocity between two horizons from RMS velocities and zero-offset times. It reports V_int, Valid? from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use RMS Velocity Dix Equation Interval Velocity
Use this seismology calculation to reproduce a stated convention, screen observations, or compare scenarios whose units, coordinate conventions, catalog selection, and model assumptions are known.
- V₁ (m/s)
- Required number in m/s. RMS velocity to the shallow horizon.
- V₂ (m/s)
- Required number in m/s. RMS velocity to the deep horizon.
- t₁ (s)
- Required number in s. Zero-offset TWT of the shallow horizon.
- t₂ (s)
- Required number in s. Zero-offset TWT of the deep horizon.
The cited overview of Seismology supplies background for the terminology and domain context used by this tool.1
How RMS Velocity Dix Equation Interval Velocity works
Dix equation interval velocity between two horizons from RMS velocities and zero-offset times. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- V_int (m/s)
- Returned number in m/s. Dix interval velocity.
- Valid?
- Returned boolean. Always true on success; non-positive Dix numerators return a dix_invalid error instead of NaN.
Limitations and assumptions
- Earth structure, source geometry, path effects, site response, instrument response, catalog completeness, uncertainty, and the fitted range can dominate the accuracy of simplified seismic calculations.
- V₁ must be at least 0.
- V₂ must be at least 0.
- t₁ must be at least 0.
- t₂ must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
For analysis or hazard decisions, retain uncertainty and provenance and compare the result with waveform processing, calibrated regional models, and guidance from qualified seismologists or the responsible agency.
