– Statement 2: The Richter scale measures the magnitude of an earthquake, which is directly related to the energy released. While the scale is based on the amplitude of seismic waves, magnitude is a logarithmic measure from which the quantity of energy released can be estimated.
– Statement 3: Theoretically, the Richter scale does not have an upper limit in its mathematical definition. Although practical measurement limitations existed with the original instruments for very large earthquakes, the scale itself isn’t bounded.
