A magnitude 3.5 earthquake has struck South Australia’s Mid North.
Geoscience Australia recorded the quake about 5km from northeast of Jamestown at about 10.30pm on Monday at a depth of 10km.
Jamestown is 65km east of Port Pirie and 217 km north of Adelaide with a population of about 1500.

About 129 people reported they felt the earthquake, some of them as far as Fullarton in metropolitan Adelaide as well as reports from Adelaide Hills.
About half an hour later, a magnitude 1.8 aftershock with a depth of about 5km was felt on the outskirts of Jamestown.
Geoscience Australia senior seismologist Phil Cummins said the 3.5 magnitude earthquake was considered small.
“I don’t think even if it occurred in a more populated area there’d be significant structural damage. It might cause superficial damage (like) things falling off shelves, broken glass, fractured plaster,” Cummins said.
“Generally, earthquakes need to be magnitude five before we start worrying about any structural damage.”
Cummins said the region where the quake occurred, near the Flinders Rangers, experienced earthquakes more often than other areas in South Australia.
However it was unclear why that was, he said.
