A magnitude-4 earthquake has rattled parts of the NSW South West Slopes, with one couple close to the epicentre saying it was "like a plane had dropped out of the sky".
The shallow quake struck north-east of Boorowa at 9:45am on Saturday, at a depth of 3 kilometres.
Geoscience Australia seismologist Hugh Glanville said it was a larger earthquake than was usually felt in the region.
