In summary, a preliminary recording captured an earthquake with a magnitude of 6.6 off the coast of northwest Western Australia. While not the largest in the region, it is the largest recorded so far. This occurrence is rare but not unprecedented, with previous earthquakes in the same region happening in 1929 and 1906. There have also been earthquakes recorded in other parts of Australia, including Gippsland, Victoria in 1966. More information about seismicity in Victoria can be found in historical documents.

Tho this is not the biggest Australian quake ( which also happened in the state of Western Australia),
Is one referring to the Exmouth earthquake in 1906?
https://en.wikipedia.org/wiki/Earthquakes_in_Western_Australia#Exmouth_1906
I vaguely remember one in Gippsland, Victoria, in 1966, mainly because it didn't affect Melbourne.

Interesting perspective on earthquakes/seismicity in Victoria

Related to Mw6.6 Quake offshore of NW Western Australia, Australia .... NOW

1. What caused the Mw6.6 quake offshore of NW Western Australia?

The Mw6.6 quake offshore of NW Western Australia was caused by the sudden release of built-up energy along a fault line in the Earth's crust. This type of earthquake is known as a strike-slip earthquake, where two tectonic plates slide horizontally past each other.

2. Was there any damage or casualties from the Mw6.6 quake?

As of now, there have been no reports of damage or casualties from the Mw6.6 quake offshore of NW Western Australia. However, it is still important to monitor the situation and be prepared for any potential aftershocks.

3. How does the magnitude of this quake compare to other recent earthquakes?

The Mw6.6 quake offshore of NW Western Australia is considered a moderate earthquake on the Richter scale. It is smaller in magnitude compared to other recent earthquakes, such as the Mw7.1 quake in Alaska and the Mw7.2 quake in Indonesia.

4. Is there a risk of a tsunami following this Mw6.6 quake?

No, there is no risk of a tsunami following the Mw6.6 quake offshore of NW Western Australia. Tsunamis are typically caused by larger earthquakes, usually with a magnitude of 7.5 or higher.

5. How can we prepare for future earthquakes in this region?

It is important to have an emergency plan in place and be aware of the earthquake risk in the region. This includes securing furniture and objects that could potentially fall during an earthquake, knowing safe evacuation routes, and having emergency supplies on hand. It is also important to stay informed and follow any evacuation orders or safety guidelines from local authorities.
