People are asking me, but what is this weird humming and rumbling noise that I am hearing in Victoria, BC on April 29, 2014? Sorry, I still have no answer for it, but looking forward for an explanation.
Last year, I reported a similar weird rumbling noise heard in Victoria and Richmond, BC. Here the video:
Source of this noise was according to newspapers the factory across the Fraser River (Mitchell Island) letting of excess steam. Did you notice a large cloud of steam? They are maybe fixing it up again. It may also be a sonic boom, created either by an Army aircraft or a meteor explosion while entering our atmosphere. But for now, I have no clues. Sorry!
