👉 The Richter scale, a widely used system for measuring earthquake intensity, is named after Julius Wilhelm Richter. It was developed in 1905 and has since become the most commonly used method of expressing magnitude from one to ten on the scale. The Richter scale is based on the energy released by an earthquake at its epicenter compared to the energy released by an earthquake at a lower or higher point along the fault line, with a range of 1-9.
