In early 2007 a United States academic claimed that coal mining in the region triggered the earthquake, although earthquake activity has been present in the area at least since white settlement first occurred.
This is in addition to reports by the former head of Geosciences Australia's earthquake monitoring group, Dr David Denholm, who stated that the Newcastle earthquake was some distance from mining activity: "The depths of the focus of the earthquake was about 13, 14 kilometres, whereas the ones associated with mining, they're actually right close to the mine, because that's where the stress release takes place"
Me not like where this is going...

The one on the 11 Mar was closer to Tokyo and a 7.9 and there was another east of this. I don't see a pattern here.
