Geoscience Australia (the government's geological organisation) says the region may be unstable for a few days and aftershocks or another quake may be felt. Duty seismologist, Dr Svetan Sinadinovski, says it was a shallow quake and the subterranean make-up of the area allowed the tremor waves to travel to Darwin without losing much energy. He says the quake was on Australia's continental shelf, which is a common place for seismic activity.
