As the sun set in Chile on Saturday, a picture of the immense structural damage wrought by an early morning earthquake had come clearly into focus, with the nation's president estimating that 2 million people had been affected in some way.
But in the grand scheme of things, geologists say this is just Mother Nature as usual.
"From our human perspective with our relatively short and incomplete memories and better and better communications around the world, we hear about more earthquakes and it seems like they are more frequent," Arrowsmith said. "But this is probably not any indication of a global change in earthquake rate of significance."
Coupled with better communication, as the human population skyrockets and we move into more hazardous regions, we're going to hear more about the events that do occur, Arrowsmith added.
