The Science of Earthquakes
The Science of Earthquakes
We usually only learn about the magnitude of an earthquake and the location of the epicenter. This infographic explains how ground waves and depth define the magnitude on the Richter Scale and the amount of destruction that implies. It also illustrates plate boundaries on the globe and the regions where most earthquakes occur. The earthquakes infographic by Weather Underground also describes hydraulic fracking and how this has increased earthquake activity in places where earthquakes don’t naturally occur.
