Washington earthquake: replicas that will be felt for days, says a seismologist

There is no tsunami threat to Australia.

Western Australians may feel aftershocks of a magnitude 5.6 magnitude earthquake for days, according to a senior seismologist at Geoscience Australia.

The Australian Joint Tsunami Warning Center detected the earthquake, reported as centered between Kojonup and Walpole, just before 1 pm local time on Sunday.

There is no threat of tsunami to the mainland of Australia, the island or the territories, says the center.

The office of Meteorology described as "disconcerting" the rocking of office buildings in West Perth.

Professor Phil Cummins told AAP he expected replicas "of diminishing size and size" to continue for some time.

While residents in Perth have reported that they felt the earthquake more than 400 kilometers away, Professor Cummins does not expect notable replicas there.

But residents in Walpole, closer to the earthquake, can feel aftershocks for days.

Those in the vicinity of the earthquake could even feel the aftershocks for weeks.

"It's a very strange event and especially that it happened in this place, on the south coast, earthquakes are more rare."

The agency did not record any earthquake of magnitude greater than 5.0 in the immediate area of ​​Sunday's event, said Professor Cummins.

"It has happened due to the accumulation of stress in the Australian crust (in the tectonic plates), strong forces are transmitted through the Australian point and when it exceeds … there is an earthquake," he said.
