All magnitude scales retain the [[logarithm]]ic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors 10³ while a magnitude 5 quake is 100 times stronger than that).<ref>{{Cite web\|title=Discovery Project 17: Orders of Magnitude\|url=https://www.stewartmath.com/precalc_7e_dp/precalc_7e_dp17.html\|access-date=2022-02-24\|website=www.stewartmath.com}}</ref> ==Richter magnitudes==
