Tsunami Effect on GPS?
I was watching the NBC nightly news tonight and they stated that the
rotation of the Earth was effected by the tsunami. According to the report the day of the tsunami was slightly shorter than standard day, which would mean that the roation increased slightly. They didn't state if the rotational change was permanent of a 1 time event. I was wondering if this induced an error in GPS positioning as the Earth isn't where it is expected to be. In my way of thinking we shifted slightly easterly. I have no idea how much of a change this is, or even if it's measurable withn the error of a GPS, but it's an interesting question. -- Geoff |
