Category:Articles using MS magnitude scale

This is a tracking category. It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the encyclopedia's categorization scheme. More information: This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set. These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications). Typically, tracking categories are automatically populated by templates invoked in pages or by the MediaWiki software (see Special:TrackingCategories for an overview of the latter).

Administrators: Please do not delete this category as empty! This category may be empty occasionally or even most of the time.

This category is not shown on its member pages unless the appropriate user preference (appearance → show hidden categories) is set.

Articles in this category have specified a magnitude scale of "MS" or "M_S" (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 M_s 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.
