Residents felt two tremors at 2.05am and again at 2.15am.

‘No noise whatsoever. I just felt the really harsh shudder and it felt like it was coming through in a line from west to east,’ local resident Laurie told ABC News.

‘It ran for five or six seconds and then was gone.’

Geoscience Australia said the rumble may have been caused by thunder in the area.

There were storms in Adelaide overnight and some residents were left without power.

‘We had a power failure since the earthquake at 2am,’ wrote Adelaide resident Heather Eckermann.

‘It’s now 6am and still no power.’

There were reports received form over 600 residents of a disturbance, Geoscience Australia said.
