Well, lets see: Earths circumfrence: 40075.04 km (400750.04 km)/(24 h)= 1669.793 km/s = 463.83 m/s Well, if you are at the equator on Earth would stop spontaneously - there would not be much left of you, as the wall next to you will hit you with supersonic speed. Allright, allright - so your not living on the equator. Lets say you are living in New York. Latitude New York is about 40° N, 40°=(2*Pi/9) (earth circumfrence*Cos((2*Pi)/9))/(24 h) = 1270 km/s = 355 m/s (rounded) You chances to survive a still rather...slim, no "slight shift".
