4.28pm Earthquake felt Moe,
Latrobe Valley, Victoria
I didn't feel the last one, so cannot compare.

Just some interesting facts about the Richter Scale. This scale is logarithmic and works in powers of ten. In other words a 4 on the richter scale is 10 times more powerful than a 3 and a 5 is 100 times more powerful than a 3. So a quake that measures 4.1, when compared to one that measures 4.8 is 7 times more powerful.
The kiwis may not agree but a quake in the 4s is a strong tremor. Much depends on how deep it occurs - the shallower it is, the harder it hits.
The
Newcastle quake of 1989 was 5.5 on the scale and did considerable damage as building codes in Australia don't really account for this sort of incident. if the tremors continue in Victroria we might just see one larger than 5. It's location and depth will determine the outcome.
