Earthquake
Nias-Simeuline – Deformation and Slip along the Sunda Megathrust 2015 Seismic rupture produced spectacular tectonic
deformation above a strip of the Sunda Megathrust about 400 km long
offshore from northern Sumatra, March 2005. Belts of uplift up to 3 m
high that are belt-parallel were revealed from coral microatolls and GPS
stations. More than 11 m of fault slip beneath the islands and a
pronounced lessening of slip trenchward is reflected by surface
deformation. The northwestern edge of the 2005 rupture is separated by a
saddle in megathrust slip from the great 2004 Sumatra-Andaman rupture.
The southern edge abuts a section, that is predominantly aseismic, of
the megathrust near the equator.
