Singapore is unfortunately located from several standpoints, and will suffer both during the pole shift and during the years after the pole shift. Being on low land and along a coast, with the potential of tidal waves from almost all sides due to its prominent location on the tip of a peninsula, it will surely be wracked by high tides which will wash most of the city away. Any survivors will find themselves in near-freezing temperatures, as the pole shift will place them closer to the new South Pole than the equator. The land will then be subject to inundation during polar melt, with the only escape route along an increasingly narrow peninsula.
