This morning, a massive 7.0 magnitude earthquake rocked Anchorage, Alaska. For reference, that's as big at 2007's famed earthquake in Indonesia, and 2010's earthquake in Haiti. Whether you've felt an earthquake or not, you likely know it's a very scary experience to live through one. According to British Geological Survey, the layman's scientific explanation of an earthquake is this: "Movements within the Earth’s crust cause stress to build up at points of weakness and rocks to deform. Stored energy builds up in the same way as energy builds up in the spring of a watch when it is wound. When the stress finally exceeds the strength of the rock, the rock fractures along a fault, often at a zone of existing weakness within the rock. The stored energy that is suddenly released as an earthquake."
Unfortunately that stored energy resulted in an enormous shifting of rock this morning in Alaska. According to eye witnesses in Anchorage, roads were ripped apart like cardboard and schools and offices were forced to evacuate.
