A 4.1 magnitude earthquake has struck underneath a mine in the NSW Upper Hunter Region.
Reports of a shake started at 1.12pm in Muswellbrook near the town of Edderton.
The epicentre appears to be directly underneath the Mt Authur coal mine near Edderton, according to Geoscience Australia.
The quake struck 3km deep and was felt by nearly 400 people north and south of the epicentre, according to Geoscience Australia.
Residents in Newcastle and Singleton said they felt the quake, as did some people in Sydney.
It’s the third quake felt in the region this year, with a 4.5-magnitude quake shaking the same mine in September.
