A magnitude 3.5 earthquake has shaken residents awake in a town in central South Australia.

Geoscience Australia recorded the quake near Jamestown, around 200km north of Adelaide, at about 10:30pm on Monday.

The earthquake struck the town of 1500 people at a depth of 10km.

Around 129 people reported having felt the earthquake, some as far south as Adelaide.

An aftershock occurred about half an hour later just a few kilometres away.

The smaller shake was only 1.8 magnitude and occurred at a depth of 5km.

Adelaide is considered at risk of earthquakes as large as magnitude 7.0 and straddles several faults.

These include the Para Fault, which runs from around Gawler, under Adelaide’s northern suburbs, under the CBD and out towards Glenelg, and the Eden-Burnside Fault under the eastern and southern suburbs.
