No risk of tsunami after northern Australia shaken by magnitude-7.6 Indonesia earthquake

The Bureau of Meteorology (BOM) says there is no risk of a tsunami to Australia after people across the north of the country were awoken by a magnitude-7.6 earthquake in waters off Indonesia overnight.

At 3:17am ACST on Tuesday, the undersea earthquake struck near the Tanimbar Islands, about 600 kilometers north of Darwin.

So far there have been no reports of damage.

The BOM said there was no threat of a tsunami to the Australian mainland, islands or territories from the quake.

Geoscience Australia (GA) also received reports of people feeling it in parts of Timor-Leste and Indonesia.

Seismologist with GA, Tanja Pejic, told ABC Radio Darwin the earthquake had a preliminary magnitude estimate of 7.6 and struck 90 kilometers below the Earth’s surface.

She said the earthquake was the largest in the area since 2010, with 2,600 reports so far from people who had felt it across the NT and Western Australia.

Kununurra, Darwin, Tennant Creek all the way to Nhulunbuy [people] were reporting light to moderate shaking,” she said

She said it was “quite likely” more aftershocks would occur.

“Certainly we have recorded one so far at a magnitude-5.4,” Ms Pejic said.

“So, much smaller. I’m not sure people would have felt that one.”

In the event of an earthquake, Ms Pejic said people should stay where they are and “drop, cover and hold”.

This involves dropping to all-fours, seeking shelter under a sturdy table or next to an internal wall, covering your head and neck with one hand and holding onto the table or wall with the other.

Immediately following the tremor, social media lit up with reports of users being woken up by shaking, many saying it was the strongest quake they had felt in the territory.

One person said they had felt shaking in Weipa, on Cape York in Queensland.

Pop star Vassy, ​​who hails from the territory, tweeted she “ran out of the house in the middle of the night” as the shaking started.

“It was rather scary. Woke us up in the middle of the night.”

Olympian and former federal senator Nova Peris tweeted that “the entire house just shook like crazy and pictures fell off the walls.”

Chief Minister Natasha Fyles urged territorians to be alert for aftershocks.

“[I] suspect a few of us are going to need a coffee or four to get going later this morning after that shock,” she said on social media.
