Category:Articles using MS magnitude scale

Articles in this category have specified a magnitude scale of "MS" or "MS" (upper-case "S"). In older sources – including the "Global Seismicity: 1900–1999" catalog of Engdahl and Villaseñor (2002) – this can be taken as indifferent use of case and synonymous with the generic short-period magnitude of Gutenberg (1945a). In modern sources and catalogs "MS" is sometimes used as a concise synonym for the long-period (broadband) Ms_BB scale.
