Effect of the Sumatran mega-earthquake on the global magnitude cut-off and event rate

The great Sumatran earthquake of 2004 allows us to assess the statistics and statistical stability of the global earthquake catalogue from the digital era. A key question is: do such mega-earthquakes continue to follow the Gutenberg–Richter (G–R) trend1, or is there an observable cut-off2?
