Shift in Earth’s Axis?

If you sense the earth days getting shorter, the earthquake in Chile may be to blame. An 8.8-magnitude temblor rocked the lowlands near Concepcion, Chile Saturday, killing over 700 and leaving tens of thousands homeless.

A study from NASA’s Jet Propulsion Laboratory showed the earthquake that struck Chile shortened the length of an Earth day by 1.26 milliseconds. Moreover, the shift in the Earth’s axis in the earthquake in Chile impacted more acutely than the Sumatran quake in 2004. The length of an Earth day is generally longest on June 21 and shortest on December 22.

Perhaps more impressive is how much the quake shifted Earth’s axis

When research scientist Richard Gross and his colleagues developed a computer model to determine the effects of the Chile earthquake, they noticed a massive temblor like an 8.8 should have moved the axis of the Earth by 3 inches (or 8 centimeters).

The question still lingers: Is Manhattan likely to get an earthquake?
