See Omori's law (and Båth's Law and the Gutenberg–Richter law), and the roughly 5% chance that this quake was a foreshock for an even bigger quake ("the 2002 Sumatra earthquake is regarded as a foreshock of the 2004 Indian Ocean earthquake with a delay of more than two years between the two events")
