    Pallavi Verma 3 months, 3 weeks ago

    The Richter scale is a logarithmic scale that measures the magnitude of an earthquake. It uses the amplitude of the largest seismic wave to determine the earthquake's magnitude. The scale ranges from 1 to 10, with no upper limit. Because it's logarithmic, an earthquake rated as 5 is ten times as powerful as one rated as 4.
