The power of the earthquake

According to NASA, the earthquake was powerful enough to decrease the length of each day:
[Dr Richard Gross and Dr Benjamin Fong Chao] found the earthquake decreased the length of day by 2.68 microseconds. Physically this is like a spinning skater drawing arms closer to the body resulting in a faster spin. (Jet Propulsion Lab link)
Scary, isn't it?
