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 value and then press the TAB or Enter key, or click anywhere out of the entry box. The program will recalculate the perception radius each time the magnitude value is changed.

The perception radii calculated by this method are estimations only, based on the empirical analysis of Australian earthquakes by Kevin McCue.
