The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. It is a base-10 logarithmic scale: an earthquake that measures 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0.

Based on my math a 6.3 would have a waveheight of 2 meters.

10^6.3 = 1 995 262.31 microns = 1.99526231 meters
