Kalgoorlie-Boulder residents woke up with a start after two earthquakes in the early hours of Saturday morning.
The first, a magnitude 3.0 earthquake, struck just after 1:00 AM at a depth of 4.02 km, the second felt around 1:15 AM and measured 2.8 on the Richter scale.
Locals took to Facebook to share their experiences, with one saying the former “felt much bigger than a 3.0” while another said they “slept through both”.
It comes just days after BHP revealed they had lost communication with some underground miners after an earthquake rocked the Nickel West site near Leinster, 370km northwest of Kalgoorlie.

The 3.5 seismic event, which occurred around 3:24 p.m. Wednesday in the Goldfields region, saw a massive blackout and loss of communication with the underground team.
A spokesman later confirmed that the miners were all safe and unharmed.
“There is nothing more important than the safety of our people,” they said.
“In line with our usual processes, operations will resume once safety testing is complete.”
No major damage or injuries have been reported since the Kalgoorlie earthquakes.
