{{Earthquakes}}
The '''Richter scale'''<ref>{{Harvnb|Kanamori|1978|p=411}}. {{Harvtxt|Hough|2007|pp=122–126}} discusses the name at some length.</ref> ({{IPAc-en|ˈ|r|ɪ|k|t|ər}}),
Because of various shortcomings of the original {{M|L}} scale, most seismological authorities now use other similar scales such as the [[moment magnitude scale]] ({{M|w}}) to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. 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>
