Strange Sounds in Wellington, New Zealand – “Wellington hum”, 14 October 2012
3 News reports that the ‘Wellington hum’ is back again. The Strange Sounds or hum were first reported 3 days ago however their source remains unknown. Possible sources may be the Wellington sewerage pump station, the Mt Victoria Tunnel ventilation shaft or the Singapore navy frigate Stalwart which was in Wellington Harbour for the past week and finally, the weirdest of all, from aliens. The Hum is now spreading and about 20 inhabitants of Mt Victoria, Mt Cook, Newtown, Berhampore and Karori complained about the Humming Sound.
