The Richter Scale is an otherwise outdated measurement system due to its inability to measure very large earthquakes. In addition to measuring an earthquake’s magnitude, we can also measure its intensity. Measuring Earthquakes Earthquakes can be measured using a device called a seismometer and a device that also records is known as a seismograph. They use an instrument to measure the magnitude of the earthquake, called a Richter scale. The big earthquakes not only occur on land but also in the sea.

Even for distant earthquakes, measuring the duration of the shaking (as well as the amplitude) provides a better measure of the earthquake's total energy. Measurement of duration is incorporated in some modern scales, such as M wpd and mB c . M c scales usually measure the duration or amplitude of a part of the seismic wave, the coda.
