Air Coupled Rayleigh Wave Speed Calculator
Rayleigh wave speed from shear velocity (≈0.92·β for ν = 0.25) compared with the speed of sound in air.
Description
Rayleigh wave speed from shear velocity (≈0.92·β for ν = 0.25) compared with the speed of sound in air.
Air Coupled Rayleigh Wave Speed Calculator is a focused tool for the following task. Rayleigh wave speed from shear velocity (≈0.92·β for ν = 0.25) compared with the speed of sound in air. It reports c_R, Supersonic from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Air Coupled Rayleigh Wave Speed
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.
- β (km/s)
- Required number in km/s. Shear wave velocity.
- c_R/β
- Optional number. Rayleigh-to-shear coefficient.

How Air Coupled Rayleigh Wave Speed works
Rayleigh wave speed from shear velocity (≈0.92·β for ν = 0.25) compared with the speed of sound in air. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- c_R (km/s)
- Returned number in km/s. Rayleigh wave speed.
- Supersonic
- Returned boolean. Whether c_R exceeds the ~0.343 km/s air sound speed.
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.
- β must be at least 0.
- c_R/β must be at least 0.
- c_R/β must be no greater than 1.
- 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.
