Another Earthquake for NZ last night, this time just a 4.7 located 7km deep and 30km inland of Dunedin. Bit of a wakeup call for Dunedinites though, they don't experience many down that way - in fact the strongest felt there since 1974. Dunedin Railway will be checking the Middlemarch line for any rock falls and track movement Im sure to be on the safe side, the mainline south wont be effected.
