Láska's empirical rule[]

This empirical rule is one way how to approximate the distance from an earthquake's epicenter. The rule is most fitting for distance in the range of 2 − 10 Mm (thousand km). The epicentral distance in thousands of km is roughly equal to the difference between arrival times of S and P waves in minutes minus 1.
