    The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale , though many other magnitudes are calculated for research and comparison purposes.

    Apr 24, 2024 · To determine the intensity of an earthquake, reports are collected about what people felt and how much damage was done. The reports are then used to assign intensity ratings to regions where the earthquake was felt.

    No matter what scale is used, quakes are detected using devices called seismographs, which measure ground motion and produce images showing how these vibrations travel over time.

    Apr 24, 2024 · This is known as intensity. Intensity values are assigned to locations, rather than to the earthquake itself, and therefore intensity can vary widely, depending on the proximity to the earthquake and the types of materials underneath and the local conditions.

    Jan 11, 2021 · Mercalli Intensity Scale depends on many factors other than the amount of energy released in the earthquake. These factors include the type of rock in the region. They also include the quality of the structures built in the area. The Richter scale is a logarithmic scale that measures the largest jolt of energy released by an earthquake.

    Magnitude scales, like the moment magnitude, measure the size of the earthquake at its source. An earthquake has one magnitude. The magnitude does not depend on where the measurement is made. Often, several slightly different magnitudes are reported for an earthquake.
