Forget Niburu for now, in September/October we experience Wormwood and that will cause the huge earthquakes and volcanoes that will contaminate the waters. Niburu comes directly after the Apocalypse. Wormwood and the Apòcalalypse are two separate events because the Apocalypse will kill far more than one third of the people, these will die in the interim period before the Apocalypse.
The USA people will start dying from the radiation spread by the 'winds from the West (Japan)' as per Jeremiah and 'they will be fanned', as they are currently with the tornadoes and internal 'hurricanes' in the USA. 'And the rivers will flow backwards' as the Missisipi is now doing. These are the 'end times', protect yourself and leave the Northern hemisphere quickly.
