Jamestown residents experience second earthquake just two weeks

SA has experienced another earthquake this morning in the state’s Mid North, just two weeks after Jamestown residents were hit.

Residents of Jamestown, in the state’s Mid North, were rocked by a 3.1 magnitude earthquake on Wednesday morning.

Occurring at 10.40am, at a latitude of -33.16 – a few kilometres north east of Jamestown – the shock had a reported depth of 1km.

Around 58 people reported that they felt the shock, from Peterborough through to Gawler.

It comes just two weeks after the town’s residents experienced a 4.2 magnitude shock with people more than 50km away reportedly feeling the tremor.

Meanwhile, Adelaide Hills residents were hit with a 2.7 magnitude shock on Monday April 15 – with a depth of 22km and shocks felt across the metropolitan area.

Each of these was strong enough for locals to feel, but not large enough to cause significant damage.

Around a dozen small quakes have been reported in the Mid North in recent weeks.

Adelaide feels regular earthquakes and sits on several faultlines.

They include the Para Fault, running from Gawler, under the northern suburbs and the CBD, and the Eden-Burnside Fault, which runs below the southern and eastern suburbs.

There is also the Willunga fault line, which snakes its way from the southern Adelaide Hills, west of the Mt Bold Reservoir, down through Willunga and out to Sellicks Beach.
