McCue Radius of Perception Calculator
This calculator uses a formula developed by Kevin McCue
that provides an empirical relationship between earthquakes of various magnitudes and the radial distance over which the effects of that earthquake should be felt by people.
The McCue formula is: Ml ~ 1.01 ln(Rp) + 0.13 which translates to: Rp ~ exp(Ml / 1.01 - 0.13)
To use the calculator just change the magnitude and then hit the TAB key or click out of the entry box. The program will recalculate the perception radius each time the values are changed.
The perception radii calculated by this method are approximations only, based on the empirical analysis of Australian earthquakes by Kevin McCue
