Strong mag. 5.9 Earthquake - NEAR S.E. COAST OF AUSTRALIA on Wednesday, Sep 22, 2021, at 09:15 am (Melbourne time)

A strong magnitude 5.9 earthquake hit 82 km (51 mi) away from Traralgon, Victoria,  Australia, in the morning of Wednesday, Sep 22, 2021 at 9.15 am local time (Australia/Melbourne GMT +10). The quake had a very shallow depth of 2 km (1.2 mi) and was felt over a large region. The shallow depth of the quake caused it to be felt more strongly near the epicenter than a deeper quake of similar magnitude would.

Fatalities and economic damage

No fatalities are known to have been caused by this earthquake, but damage to buildings and infrastructure was moderate in the areas near the epicenter.

This was the 2nd worst quake in Australia during recorded history.

Strong and scary quake in Australia luckily left little damage in its wake

Locations of people who felt the quake in Australia yesterday

A large earthquake with a magnitude of 5.9 hit Mansfield, in the state of Victoria, Southeast Australia on the morning of September 22, 9:15 am. The last time a quake hit the area was 9 years ago near Thorpdale (Baw Baw) with a magnitude of 5.2 and another 21 years ago in South Gippsland with a magnitude of 5.0.
It was nothing short of a miracle that there was very little damage and no serious casualties reported at the time of writing from this heavy and shallow quake, which was felt as far as 600 km away from its epicenter, all the way to the Central Coast of New South Wales. Our monitoring service at VolcanoDiscovery was bombarded with over 10,000 reports of the quake (our highest number of reports from a single quake).
Thousands of people reported shaking, windows rattling, the feeling of heavy trucks passing by, swaying water and much more, even before official quake agencies released a quake report. Many residents reported evacuating their homes and some suffered from power cuts. News bulletins showed some fallen debris from buildings in Melbourne, Australia's second largest city, which miraculously did not fall on people during this early hour.
We believe that strong building codes and sound construction practices in Australia helped protect against more severe damage. There were also lesser aftershocks that were also felt by some residents, which also didn't contribute to significantly to existing damage. In the township of Seymour, Victoria, about 116 km away from the epicenter, one user said that "internal doors swung open, small items fell on shelves". Another user described "Vibration as if a tank was happily hopping by just outside the house. I was standing so had to grab on to the kitchen counter." Other feedback sent to us included "pictures fell of the walls" and " There seemed to be a thump of some sort then very significant rattling of crockery".
A scary morning indeed, but at 5.9 it could have been much worse. We're happy that the damage was very limited and no serious casualties were reported.

Significant magnitude 5.9 quake hits 62 miles northeast of Pakenham, Victoria, Australia in the morning

5.9 quake 22 Sep 9:15 am (GMT +10)
5.9 quake 22 Sep 9:15 am (GMT +10)
The European-Mediterranean Seismological Centre (EMSC) reported a magnitude 5.9 quake in Australia near Pakenham, Cardinia, Victoria, 4 hours ago. The earthquake hit in the morning on Wednesday, September 22nd, 2021, at 9:15 am local time at a very shallow depth of 1.2 miles. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Our monitoring service identified a second report from Indonesia's Meteorology, Climatology, and Geophysical Agency which listed the quake at magnitude 5.9 as well. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 5.7, the United States Geological Survey at magnitude 5.9, and Geoscience Australia (GeoAu) at magnitude 5.9.
Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Moderate shaking probably occurred in Jamieson (pop. 270) located 16 miles from the epicenter, and Mount Buller (pop. 2,600) 24 miles away.
In Mansfield (pop. 4,800) located 32 miles from the epicenter, Traralgon (pop. 24,600) 51 miles away, Warragul (pop. 15,300) 52 miles away, Morwell (pop. 13,600) 52 miles away, Lilydale (pop. 16,200) 57 miles away, Pakenham (pop. 45,900) 62 miles away, and Melbourne (pop. 4,246,400) 78 miles away, the quake should have been felt as light shaking.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.

Additional info

The southeast coast of Australia has been rocked by a large earthquake, shaking buildings in Melbourne, Sydney and Adelaide. Eyewitness accounts are flooding in of residents fleeing apartment blocks in Melbourne after feeling strong tremors for up to 30 seconds. Social media has been inundated with images from inner-city suburbs which show rubble strewn across streets believed to be due to quake damage. Early reports suggest at least 46 buildings have been damaged across Victoria in the earthquake. (reference #13055)

A magnitude-5.9 earthquake struck in southeastern Australia on September 22, 2021, at 9:15 am local time. This is the largest earthquake in Victoria in the two centuries of European settlement. Aboriginal Australians have lived in eastern Victoria for around 40,000 years [...] Initial insurance claim data indicates that at least 1,500 buildings suffered minor damage such as fallen masonry (e.g. chimneys) and cracks to plaster, render and walls. (reference #13061)

What is Intensity and the Mercalli Intensity Scale?


The amount of shaking that occurs on the surface due to an earthquake is called the intensity. It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.
Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.

31 aftershocks for this quake

For this earthquake, 31 aftershocks have been detected so far. The strongest was a magnitude 4.1 quake that hit 18 minutes after the mainshock in 3.8 km (2.4 mi) distance, in Australia: Rawson, VIC, on Wednesday, Sep 22, 2021 on 09:33 am (Melbourne local time GMT +10).
The most recent aftershock occurred 3 years ago Australia: Rawson, VIC, and had a magnitude of 2.2.

What are aftershocks?


Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.
[More info]

What about this quake?


Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface of approx. 79 km2 (=31 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 15 km (10 mi).

Earthquake statistics

Average number of earthquakes

Based on data from the past 14 years and our earthquake archive back to 1900, there are about 12.6 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):
  • Mag. 5 or higher: 0.14 quakes per year (or 1 quake every 7.1 years)
  • Mag. 4 or higher: 0.25 quakes per year (or 1 quake every 4 years)
  • Mag. 3 or higher: 1.23 quakes per year
  • Mag. 2 or higher: 11.4 quakes per year
The area where this quake occurred has a moderate level of seismic activity. However, It has had at least 2 quakes above magnitude 5 since 2010, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.
