An earthquake measuring 4.6 on the Richter scale has shaken residents of Kalgoorlie-Boulder this morning.
The quake started just after 8am, with its epicentre about 30 kilometres from the inland city at a depth of 15km.
Concerned residents immediately took to Facebook and Twitter.
South Kalgoorlie resident Samantha Duddy, who lives on Ardagh Avenue, says she never usually feels blasts from the city's famous Superpit.
"Where we are, we never feel the blasts and this was definitely different," she said.
"There were two tremors, the house shook, then it was about 20 seconds and it shook again.
"It was a sustained shake so it definitely wasn't the usual blasting, it was definitely an earthquake.
"My cousin lives on the other side of town and she felt it as well, so I'm hoping there's not more to come."
Helen Ducey works on the top floor of the heritage-listed McKenzie Chambers on Hannan Street and she said she though glass panels within the building would shatter.
"If I was on the ground floor I would have run out of the building," she said.
"The whole building was shaking, and maybe it wasn't as bad at ground level but on my level it felt really bad."
Grand Hotel publican Ken Smith told Radio 6PR that he was in bed when the earthquake hit and he immediately contacted his family, then went next door to check on damage to his Boulder hotel.
He said there was no damage to his hotel, however his granddaughter told him that Kalgoorlie Town Hall had been evacuated.
Geoscience Australia said in its unfinalised report that the earthquake could have been felt by people up to 125km from the epicentre and may have caused damage up to 10km away
The city was last hit by a major earthquake on April 20, 2010, with a magnitude 5 earthquake causing major damage to heritage buildings in Boulder and Kalgoorlie.
