NOAA magnitude[edit]

The NOAA magnitude for this earthquake, the first shock of the doublet, is actually 5.8 M_s , not 7.6 - see the relevant page in the significant earthquake database, although I strongly suspect that it is a typo for 6.8 M_s  going by the quote from Soloviev & Go (1974) in the comments section, which gives 6.75 M_L . 6.8 matches well with the ISCGEM catalogue magnitude of 6.7 M_w  (the value used in the ANSS page).

Doublet[edit]

The two earthquakes about 3 hours apart are regarded as an earthquake doublet - see Daryonon et al. 2012 and Nakano et al. 2010. I've added details of the second shock to the infobox, but the article name should be changed to 1926 Padang Panjang earthquakes, similar to the 1943 Alahan Panjang earthquakes and the March 2007 Sumatra earthquakes, subsequent doublets that are interpreted to have ruptured the same parts of the Great Sumatran fault.
