A magnitude 3.6 earthquake has struck Port Hedland at a depth of 10km.

Dozens of people woke up to the tremor, which hit Western Australia‘s Pilbara region at 4.49am local time (7.49am AEDT) on Wednesday. 

‘Was in a deep sleep and woke me up, wasn’t sure if it was a thud or earthquake in the south,’ one local wrote on social media. 

‘Definitely felt that one, I thought a train crashed,’ a second wrote. 

A third commented: ‘Yep, heard more than felt it. And a few smaller ones afterwards. Pets freaking out.’

Minor tremors may have been felt in Boodarie located 6km from the epicentre, South Hedland about 10km and Wedgefield 14km away. 

There is no tsunami threat to Australia, the Bureau of Meteorology confirmed.
