“Australia is very geologically inactive.”
Isn’t Australia on the Western half of the so-called, “Ring-Of-Fire”?
New Zealand gets plenty of earthquakes, so it would stand to reason Australia would too.
They may look close together on a world map but New Zealand and Australia are 2,500 miles apart.
New Zealand is on the ring of fire. Australia is in the middle of a continental plate.
I think that ring of fire directs over to the Jakarta
South China Sea and Indian Ocean region.
I think Australia is East of there.
It’s more in-line than I thought. From what others are
saying though, the ring of fire seems to veer/end north
and a little less west of Australia than I had thought.
Still, Australia isn’t known for earthquake activity.
Melbourne is on the far side of Australia from the ring
of fire region.
