What is the scale used to measure earthquakes - Earthquakes can be measured in two ways. One method is based on magnitude—the amount of energy released at the earthquake source. The other is based on intensity—how much the ground shakes at a specific location. Although several scales have been developed over the years, the two commonly used today in the United States are the moment ...

 
Mar 23, 2023 · Therefore, the greater the magnitude, the more energy is released during the earthquake. Following this logic, this would be a logarithmic scale. Put another way, the increase in magnitude of 1 unit would correspond to the increase in energy release of 30 units. And it is based on this theory that the Richter Scale arises. . Classical century
