Regional areas rattled by 5.7 earthquake
The biggest West Australian earthquake in 20 years rattled homes across the South West on Sunday afternoon, with people feeling the tremors from Perth to Albany.
Walls shook and windows bowed in the 5.7 magnitude earthquake, which took place near Lake Muir about 124km northwest of Albany at 12.56pm.
It was the seventh earthquake in WA this month, and the fifthbiggest on record.
The tremors could be felt over a 300km radius and were picked up by 13 reporting stations in WA and South Australia.
It preceded four tremors, in the same area, from Sunday to Wednesday.
No injury or damage is known to have occurred.
Senior seismologist at Geoscience Australia Phil Cummins, who spoke before the earthquake was upgraded from a 5.6 magnitude to a 5.7, said one that size was rare in Australia.
“A 5.6 quake is quite large — you might get a 5.6 every few years in Australia,” he said.
As the quake’s epicentre was in a remote part of WA where there were few buildings it was unlikely to cause any serious damage.
Mr Cummins said aftershocks may be felt for several weeks.
“It’s always possible these could be leading up to something bigger, but I think it’s more likely we’ll see a decrease in size and frequency,” he said.
“It’s difficult to say if it’s random statistical clustering or if there is something else going on.”
Walpole IGA manager James Griffiths said his shop, which was about 50km away from the epicentre, shook for several moments during the bigger earthquake.
“It was quite a substantial shake,” he said.
“It really rattled the whole shop and you could hear it quite well.
“It was also felt in other places. One of my staff who were at their house in Myalup, heard it there.”
The earthquake could be felt from Perth to Hopetoun.
