Hundreds of Western Australians reported feeling the ground move early this morning, after a 4.7 magnitude earthquake which was part of a wider "swarm" of minor quakes hit east of Perth.
One woman who spoke with radio station 6PR claimed her bed had lifted several centimetres off the floor.
The 5.24am earthquake was recorded west of Wagin, about 230 kilometres south-east of Perth, at a depth of eight kilometres. It was the largest rumble in a series of dozens of quakes over the past seven days.

Geoscience Australia (GA) warned Western Australians to expect more aftershocks throughout the morning.
GA senior seismologist Tania Pejic told 6PR there had been a "swarm" of earthquakes recorded over the past week.
"There's no good explanation as to why swarms occur," she said.
"What they are is a big number of earthquakes occurring over a small period of time without a discernible main shock."

Ms Pejic said GA had recorded in excess of 30 earthquakes in the area over the last seven days.
It was not possible to know if this morning's earthquake was going to be the peak of the swarm, she said.
In the first hour after the earthquake, more than 500 reports were submitted by the public, GA said.
By 6.38am, an aftershock with a preliminary magnitude of 3.6 had been recorded by GA's National Earthquake Alerts Centre.
There are so far no confirmed reports of damage.
