Earthquake in Victoria (Australia)

[Mike Cecil]

Check out this site: You'll be surprised at how many, where, and what magnitude, earthquakes occur along the Eastern Seaboard of Australia....

Simplisticly, while the majority of the world's earthquakes are concentrated along the edges of tectonic plates (eg like the trench just east of NZ) , the shifting along plate boundaries also causes the fault lines across the plate surfaces to build up pressure: these then have to move to reduce those forces. There are quakes happening all the time (which is good: relieves the pressure in small increments) , but they are mostly below the threshold of being 'felt' by humans.

Clear as mud, eh?
