26 gru 2004 · Map showing aftershock locations for the first 13 weeks after the 26 December 2004 earthquake from the NEIC (yellow dots, with radii proportional to seismic magnitude).
Sunda Trench. The Sunda Trench is a subduction zone extending in an arch from the Northwestern tip of Sumatra to Flores in Eastern Indonesia. A strong earthquake in this zone can generate a tsunami that arrives at the coast within 20 minutes, leaving little time for issuing an early warning.

25 maj 2012 · We were able to obtain the detailed geometry of the subducting Indian Plate by constructing iso-depth contours for the subduction earthquakes at depths of 30–140 km. The strikes of the contours are oriented approximately N-S, and show an “S” shape in map view.
2 mar 2006 · These data show that the earthquake was generated by rupture of the Sunda subduction megathrust over a distance of >1,500 kilometres and a width of <150 kilometres.
