Earthquake Zones in Australia: Where Seismic Activity Is Most Common

Australia experiences intraplate earthquakes, mostly along continental margins where tectonic stresses concentrate:

1. Southwest Western Australia – Southwest Seismic Zone (near coast).
2. Northern Territory – Tanami Region (Australian/North Australian plate interaction).
3. Central Australia – Alice Springs, Tennant Creek area.
4. Eastern Seaboard – NE New South Wales, SE Queensland, Victoria (subduction zone influence).
5. South Australia – Cooper Basin region.
6. Tasmania – Western part of the state.

While less frequent and severe than plate-boundary zones, earthquakes can occur anywhere; building codes account for this risk.
