Earthquake in Chile :(

[Éyru]

Kaltxì ma aysmukan ulte aysmuke!
I'm from Chile, and as you know we had on Friday's night, one of the most powerful earthquakes in History....The earthquake even moved the Earth's Axis 8 centimetres, making the day just a little thousandth of seconds shorter....
Well, my doubt is: How would you say Earthquake in Na'vi???
