Magnitude 4.1 earthquake strikes regional NSW – as Aussies feel tremors in Penrith, Central Coast and Hunter Valley

Thousands of residents have been left without power after a magnitude 4.1 earthquake rocked regional NSW.

The quake was recorded 7km from Denman in the Upper Hunter Region, 250km north of Sydney, at a depth of 10km shortly before 12.15pm on Tuesday.

Over 300 people reported feeling the earthquake in the Hunter Valley, Central Coast, Scone and Penrith in western Sydney, according to Geoscience Australia.

Power supplier Ausgrid reported more than 2,500 addresses are currently without power. 

No injuries have been reported. 

‘What the hell is going on?’ one wrote on social media platform X.

‘Felt in the Hunter Valley,’ a second added.

A third added: ‘How many times is that now in the last 6 months?’ 

There is no tsunami threat to Australia, the Bureau of Meteorology has confirmed. 

Senior seismologist Dr Hadi Ghasemi from GeoScience Australia described it as an ‘earthquake swarm’. 

‘In earthquake swarms, you have a series of the earthquakes with similar size magnitudes — it’s not like an aftershock sequence,’ he told ABC. 

‘In this region, since the magnitude-4.7 in August, we’ve recorded over 50 earthquakes, four of them with magnitudes larger than 4, including the recent one.’  

Dr Ghasemi warned residents of the possibility of further tremors being felt.

‘All of the previous magnitude-4 ones in this region, they were followed by smaller aftershocks,’ he said.

‘But then again, with the swarm activity this kind of activity may continue for months or even years to come.’
