Just after midnight on Thursday, an earthquake was recorded at Robertstown with a magnitude of 2.0 and a depth of 10 kilometres.
According to Adrian Menzel, who lives four kilometres north of Robertstown, on the Worlds End Highway, he was first alerted by a “noise in the distance”.
At the time he was working in his office updating the Robertstown website, while his wife Val lay in bed.
Soon after Mrs Menzel confirmed the same noise with Mr Menzel then phoing FiveAA and speaking to Peter Godfrey to further confirm details or if anything was experienced in Adelaide.
While the radio announcer had not received any reports, Mr Menzel said, “Seeing that I heard it I will be reporting it on the earthquakes website and to see if it has been recorded”.
Mr Menzel turned to the Geoscience Australia Earthquakes to lodge the information.
“Not long after I had rang FiveAA, Peter announced on air for any listeners to ring him if they had heard and/or felt it,” Mr Menzel said.
“He also had looked at the website and could see that it was recorded.”
While still viewing the website, Mr Menzel also noticed that at 11:52pm on Wednesday, February 7, almost a half an hour before the Robertstown earthquake, another was recorded north-west of Leigh Creek with a magnitude of 2.1.
