For the record: this article was split 24 Nov. 2017 from Seismic magnitude scales, which was originally "Seismic scale", created in 2006. For the earlier history see here. ~ J. Johnson (JJ) ( talk) 22:31, 24 November 2017 (UTC) reply

The recent change of name from the plural form to the singular form is deemed incorrect. Discussion at Talk:Seismic magnitude scales#Seismic scales: not singular. ♦  J. Johnson (JJ) ( talk) 21:09, 23 March 2019 (UTC) reply
