Darwin shaken by Timor-Leste earthquake

The 6.4-magnitude quake hit at a depth of 65km about 12.06pm ACST on Friday, according to Geoscience Australia.

"I was in my office in Darwin three stories up and monitors shook and door frames creaked," Ben Tuffnell told AAP.

"You could feel the whole building shake. All the staff came out of their offices saying it was one of the stronger tremors in recent years.

"It lasted for a good 30 seconds."

The Bureau of Meteorology confirmed there was no tsunami threat to Australia.

"Wow I just felt the earth move here in Darwin! An earthquake just shook our Office building here in Casuarina! Anyone else feel it?" William Daw said on Facebook.

"Decent earth tremor in Darwin just then," Mel Court reported via social media soon after.

"That felt weird. Nice little tremor there, Darwin," Ruth Davies said on Twitter.

Timor-Leste is 687km north-west of Darwin.
