  1. aThe preferred model for the 5 July 2005 Mw 6.6 Nias event and for the 9 September 2010 Mw 7.2 Simeulue event was taken to be at the lobe of a local maxima closest to the positions given by the teleseismic catalogs instead of at the global maxima
  2. bThis earthquake was modeled as an Mw 6.56 event equivalent to the energy release by the combined Mw 6.4 and 6.3 events because these events occurred too close in time and space to resolve the individual displacements at the GPS stations
