Earthquake facts:
- The 1968 Meckering earthquake was magnitude 6.5.
- The 1988 Tennant Creek earthquake was Australia’s biggest on record, at magnitude 6.6.
When was the last major earthquake in Victoria?
No large (magnitude 6 or above) earthquakes have occurred in Victoria since European settlement in the early 1800s but geographers such as Hills (1963), Bowler and Harford (1966) and Twidale and Stehbens (1978) identified Recent fault scarps in the state left by large earthquakes in prehistoric times, some of which
Does Victoria Australia get earthquakes?
A magnitude five event occurs in Victoria every seven years, and we’ve been lucky so far. We know that it’s very difficult to predict the location of these, and we know that they are occurring. “So, at some point in the future, one of these magnitude five earthquakes will hit an urban centre.
What was the earthquake in Victoria?
A magnitude 3.4 earthquake has shaken the Victorian town of Mansfield, about 180 kilometres north-east of Melbourne.
What was Australia’s strongest earthquake?
The strongest earthquake in Australia happened on 05/23/1989 in the Macquarie Station; New Zealand region with a magnitude of 8.2 on the Richter scale. The earthquake also triggered a tsunami, leading to further victims and destruction.

How many earthquakes Does Victoria have a year?
More than 200 small earthquakes are recorded each year in this region, several of which are felt. Those large enough to cause damage occur roughly once each decade, whereas the very large subduction zone earthquakes happen centuries apart.
Has Victoria Australia ever had a tsunami?
Even though the overall tsunami risk to Victoria is lower than many other parts of the world, a tsunami may still impact the Victorian coast. The largest tsunami to affect Victoria in recent times occurred in May 1960 after a 9.5 magnitude earthquake in Chile.
Is Victoria Australia on a fault line?
The Cadell Fault is a north-south trending intra-plate geological fault in the Riverina area of New South Wales and Victoria within Australia.
Is Victoria on a fault line?
The second major structural break in Victoria is the Baragwanath Transform, which occurs along the eastern side of the Selwyn Block. This transform fault divides the Lachlan Fold Belt into two terranes, the Whitelaw Terrane to the west and the Benambra Terrane to the east.
How deep was Melbourne earthquake?
The quake, which started near Woods Point at a depth of 12km, was also felt in Sydney, Canberra, Adelaide and even as far as Launceston, Tasmania. I and the co-author of this article, Dee Ninis, work as earthquake scientists at the Seismology Research Centre. Researching earthquakes is our life’s work.
Did an earthquake hit Melbourne?
Despite being relatively small on a global scale, the September 22 earthquake that struck at 9.15am was the biggest onshore earthquake ever recorded in Victoria. The epicentre of the tremor was at Woods Point, a town 179km north east of Melbourne’s CBD, with the tremors felt up to 700km away.
When did Melbourne last have an earthquake?
The state of Victoria, Australia, was shaken by its biggest onshore earthquake in recorded history on 22 September. Some buildings were damaged but no one was seriously hurt. The magnitude 5.9 earthquake struck at 9:15am local time, according to Geoscience Australia.
Has there ever been a 10.0 earthquake?
No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake.
Why Australia is free from earthquake?
When it comes to earthquakes, living in Australia is much safer than other parts of the world, as Australia is well away from tectonic plate boundaries where large earthquakes occur more frequently.
Is earthquake rare in Australia?
“On average, Australia experiences two earthquakes with magnitudes greater than 5 per year, which is a rather high level of seismicity for a stable continental region. “In the past century, about 27,000 earthquakes were recorded in Australia, and over 90 per cent of these earthquakes occurred at a very shallow depth.”
Could Victoria have another earthquake?
“There is still the chance of significant aftershocks to impact Victoria,” he said, but he added they were unlikely to exceed the magnitude-5.9 quake.
Why is Victoria getting earthquakes?
The earthquake that hit Victoria on Wednesday morning is probably the result of tectonic plate pressure in New Zealand that built up slowly and then released suddenly in a rupture at a fault about 130 kilometres north-east of Melbourne.
How many aftershocks did Victoria have?
Two aftershocks have rocked north-eastern Victoria, weeks after a record-breaking 5.9 magnitude earthquake struck the state. The aftershocks were recorded by Geoscience Australia at Rawson in Baw Baw Shire this morning.
Where do 80% of all earthquakes occur?
the Pacific Ocean
Where Do Most Earthquakes Occur? Some 80 percent of all the planet’s earthquakes occur along the rim of the Pacific Ocean, called the “Ring of Fire” because of the preponderance of volcanic activity there as well.
Which city in Australia has the most earthquakes?
Although Australia experiences few earthquakes by world standards (Gibson 2010, McCue 2010), Adelaide is the most earthquake-prone city on the continent, with moderate earthquakes (magnitude five to six on the Richter scale) occurring frequently enough to be a potential danger (Doyle et al. 1968).
