Earthquakes

Earthquakes. How do we measure an Earthquake?. We can measure Earthquakes using one of two main scales. Richter Scale Mercalli Scale. Mercalli Scale. In 1902 Guiseppe Mercalli devised a scale for measuring the intensity of an earthquake by relating it to the amount of damage it caused.
