An earthquake exceeding magnitude 7 occurs somewhere in Australia every 100 years or so. A typical site in Australia will be within 50 km of a magnitude 7 event every 100,000 years or so. … These are unlikely to ever occur within Australia.
What is the likelihood of an earthquake in Australia?
About every ten years Australia experiences a potentially damaging earthquake of magnitude 6.0 or more such as the magnitude 6.5 Meckering earthquake in October 1968.
What is the likelihood of a large earthquake striking a major Australian city in the next hundred years?
Intraplate earthquakes are caused by the continents moving and stretching. Due to Australia moving so dramatically and quickly it creates more tension in the earth’s crust resulting in intraplate earthquakes. In the next 100 years the 70mm per year could turn into a 1000mm a year.
When was the last major earthquake in Australia?
On 16 September 2018, a magnitude 5.3 earthquake reverse-faulting occurred near Lake Muir in southwest Western Australia. While not one of the largest earthquakes recorded in the Southwest Seismic Zone, it was widely felt, including in the Perth metropolitan area over 300 km away.

Is there a fault line in Australia?
The Darling Fault is one of the longest and most significant faults in Australia, extending for at least 1500 km in a north–south orientation near the west coast of southern Western Australia. The fault zone is very ancient and initially formed during the Proterozoic Eon. …
Where is the most dangerous place to be during an earthquake?
If you are outside, stay outside.
Once in the open, get down low and stay there until the shaking stops. The area near the outside walls of a building is the most dangerous place to be. Windows, facades, and architectural details are often the first parts of the building to collapse. Stay away from this danger zone.

The largest tsunami impacts have been recorded along the northwest coast of Western Australia: In 1977 a tsunami travelled inland to a point six metres above sea level at Cape Leveque, WA. In 1994 a tsunami travelled 300 metres inland in the Onslow-Exmouth region of WA.
Which Australian cities are at risk of an earthquake?
Canberra is the capital city at highest risk of an earthquake, because of its proximity to one of Australia’s most active faults, at Lake George.
Can an earthquake split the earth?
Certainly, earthquakes can cause cracks to form in the Earth, such as happened during the Loma Prieta earthquake in 1989. However, these cracks are generally quite small and only rarely do they exceed a meter or two in width. And certainly these cracks don’t again close up and swallow somebody whole.
Where is Australia’s most active earthquake zone?
While a significant earthquake is yet to occur specifically on the Darling Fault, the lengthy crack sits just to the east of the South West Seismic Zone – the region with most of Australia’s earthquake activity.
What is the most dangerous fault line in the world?
The New Madrid Seismic Zone (/ˈmædrɪd/), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.
