Tracking The Geologic Impacts Of Earthquakes

NPR  

Tracking The Geologic Impacts Of Earthquakes The earthquake that shook Chile last weekend was powerful enough to push up the Andes a few feet, shift Earth's axis and even speed up the planet’s spin. Mr. STEIN: That's right, and so in this earthquake we calculate that the coastline of Chile for three, 400 miles was uplifted several feet during this earthquake. Mr. STEIN: Well, what's happening is that the denser material, the plate, what we call the Nazca Plate, the oceanic material which gets shoved underneath the continent because the continent is just a little less dense, you're basically jamming dense material deeper into the Earth, and just like a spinning skater that we watched during the Olympics, when she brings her arms in, she spins faster. Mr. STEIN: Okay, if we think of if we represent an earthquake's magnitude by - or size - by the volume of a sphere, then imagine a ping-pong ball.
