Hi all,
First off, some additional Codex/Health info links:

Also, i've had a look at the 'iris' website and i noticed that most earthquakes that appear on the map do fall on seismically active regions - especially around Fiji, Indo etc..
In Australia though, i find it curious to say the least, since we are in an inactively seismic region. This small link could be of interest:
