There is no threat of a tsunami to Western Australia's Pilbara despite the area enduring a 5.4 magnitude earthquake overnight.
The Bureau of Meteorology noted that around 9pm last night Marble Bar near Port Hedland and Karratha was hit by the earthquake, which lasted around 20 seconds.
Geoscience Australia said the earthquake was recorded at a depth of 10 kilometres and produced three aftershocks with preliminary magnitudes ranging between 2.6 and 3.2.

"In the last five years there have been only two earthquakes larger than magnitude 4.0 recorded within 200 kilometres of this earthquake's epicentre," Geoscience Australia noted.
"The state of Western Australia has had 23 earthquakes of magnitude 5.0 or larger since 2000. The largest was offshore Broome in July 2019, at magnitude 6.6.
"On average, around 100 earthquakes of magnitude 3 or larger are recorded in Australia each year."

Australia experiences fewer earthquakes than other countries due to the distance of the continent from the boundaries of the world's tectonic plates.
