Dip-slip faults can rupture within the downgoing Australian Plate as well; the 2009 magnitude 7.6 earthquake near Padang was caused by reverse faulting at a depth of 80 km (50 mi).[10] Occasionally, the subduction plate interface ruptures in earthquakes that reaches the trench, triggering large tsunamis such as in 1907, 2004 and 2010.[11] The Great Sumatran fault was the source of the 1994 Liwa and 1995 Kerinci earthquakes.
