Earthquake hits two weeks after it was rocked by a 4.2 magnitude shock

A second earthquake has hit a regional Aussie town just two weeks after it was rocked by a 4.2 magnitude shock.

Residents of Jamestown, about 217km north of Adelaide, felt the rumble around 10.40am on Wednesday. 

Around 60 people reported that they felt the earthquake, from Peterborough through to Gawler. 

Geoscience Australia, the government agency which reports on significant earthquakes, said the quake occurred at a depth of five kilometres.

It comes just two weeks after a 4.2-magnitude tremor hit the town, which could be felt as far as 50km away. 

A 2.7-magnitude shock also hit the Adelaide Hills on Monday, April 15, with a depth of 22km.
