On Feb 22nd a 6.3 magnitude earthquake hit Christchurch, NZ. More than 60 deaths, 75% of the city without power, and billions of dollars in damages. The weird part? It was hit by an even more powerful quake five months ago, and nothing happened.  Tonight, we’ll share a few of the details on quakes, explain some of the science behind them, then go on a sciencey tangent about plate tectonics, volcanoes and fault lines, and even the end of the world!
