A big earthquake in one of Australia’s most seismically active states could be a warning that earthquakes of this magnitude could strike, and could shake the Australian capital, Brisbane.
The quake struck about 1:15pm local time (10:15 GMT), triggering a series of aftershocks.
It was the biggest quake to hit Australia since the 1964 Alaskan earthquake that killed more than 4,000 people.
It was the largest earthquake to strike Australia since a devastating 2011 earthquake in central China that killed over 500 people.
“We have a big earthquake, so it’s going to be a big shake,” said Mike Tait, a geologist at the University of Western Australia.
“You might not have any power, there may be a bit of a blackout, so we’re all hoping that everything is OK.”
In the past two weeks, a series for the Pacific Northwest has occurred, with two quakes measuring 5.0 on the Richter scale.
On Sunday, a magnitude 6.2 earthquake shook the western US, knocking out power in parts of Colorado and Utah and damaging homes and businesses.
A second quake measuring 6.3 on the U.S. Richter Scale, which measures tremor intensity, occurred in British Columbia on Monday night.
The U.K. has a history of quakes bigger than the one in Queensland, which was magnitude 6 on Sunday, but its epicenter was much smaller.
In Queensland, at least 14 people were killed when a 4.8 magnitude quake in April 2011 shook the state, which had just seen its first major earthquake in 25 years.ABC/wiresTopics:earthquakes,earth-quake,crispus land,brisbane-4000,qld,australiaContact Andrew HarnishMore stories from Queensland
