Surprised by Wakefulness

Woke up at 3 am this morning and tuned into Fox Channel. First surprise. Next surprise was the 8.8 quake in Chile. What is it with quakes this year? Is it caused by the lightening of the snowpacks at the poles changing the weight on the crust of the sea bottoms? I think so but no one has confirmed that so far. USGS where are you? It is entirely predictable that this would happen. Look at the lake bottom of Lake Erie for an example.
