An earthquake is still being felt from the 5.8 magnitude earthquake in Victoria, which shook the residents of Canberra, the south coast, the south-west slopes, Geelong and Melbourne on 22 September.
Geoscience Australia reported that the epicenter of the 9:15 earthquake was near Rawson, Victoria at a depth of 10 km.
It is believed to be the largest earthquake in Victoria in a century or more.

Geoscience Australia recorded nine aftershocks in the 24 hours following the first earthquake, which ranged from 2.4 to 4.1.
There have been a dozen tremors since then to a maximum of 3.1 magnitude.
The region has experienced six small quakes since Monday, October 4, including a magnitude 3.1 earthquake on October 6 at 4:12 a.m., but less than a dozen reports have been experienced in the greater Victoria region.
According to Geoscience Australia, earthquakes of magnitude less than 3.5 rarely cause damage.
At the time of the first earthquake, Geoscience Australia senior seismologist predicted Dr. Hadi Ghasemi that there could be more, but they would become less frequent.
“However, it is important to note that it is not possible to predict exactly when or how large these earthquakes may be, or when the sequence will drop to a point where they can no longer be detected,” he said in a statement.
The organization has sent equipment to the area to measure seismic signals from aftershocks. They also analyze satellite data for earthquake movements since the earthquake.
“All of this information helps our researchers better define the source of the earthquake, including the active fault and depth of the main event,” said Dr. Ghasemi.
“This data can be used to improve hazard estimates and guide building design that helps make our community safer.”
