Powerful earthquake rocks South Australia

A powerful earthquake has rocked South Australia. 

The 4.2 magnitude tremor hit Jamestown in the state’s mid-north, around 200km north of Adelaide, just after 4pm on Wednesday.

One local said the shock could be felt ‘far and wide’, amid reports the quake could be felt as far as 50km away. 

‘Sounded like a train going down Sixth Street, no wonder my poor old house is cracking up!’, the local wrote on social media. 

Another reported that ‘there has been several aftershocks since’, while a local in Booleroo around 45km said it had rocked their garden sheds. 

The tremor has generated almost 180 ‘felt’ reports on Geoscience Australia’s website, with the true number likely to be far higher. 

Chief Seismologist David Love told The Advertiser ‘further shocks are likely’.
