Chile quake shortened our days according to NASA

This is an article from the Washington Post that says the Chile quake shortened our days. It says the he length of the day got shorter by 1.26 microseconds (millionths of a second), which doesn’t seem like much, bit the axis, moved by 2.7 milliarcseconds (about 8 centimetres or 3 inches).” That’s alot. I wonder what these changes are going to bring.
