ORANGE residents on Sunday felt the tremors of the region’s second earthquake in the space of a week, and its third of 2017.

According to the Federal Government’s Geoscience Australia Earthquakes website, a 2.5 magnitude earthquake was registered at 1.51pm.

According to the Geoscience Australia website, the location of the earthquake was approximately 20 kilometres north of Orange, near Mullion Creek.

At this stage it is unknown what depth the earthquake originated at.

According to the website another earthquake was recorded in regional NSW on Sunday, this one near Katoomba, registering a magnitude of 2.0 at a depth of 10 kilometres.

The Mullion Creek earthquake is the second to be felt in the Orange region in the last week, after a 3.5 magnitude earthquake hit just south-west of the Newcrest-operated Cadia Valley Operations (CVO) gold mine site at about 2.33am last Sunday.

That earthquake lasted only seconds at a depth of 10 kilometres, with Geoscience Australia estimating it could be felt up to 38 kilometres away.

At about 2.30am on Good Friday this year, a 4.3 magnitude earthquake lasting seconds hit just 30 kilometres south of the city, five kilometres west of the CVO site.

The tremor brought a halt to production as 56 people were shepherded to safety chambers, before later escaping to the surface at 9.30am once access points were deemed safe.
