What Is the Earthquake Scale Called?

The first widely-used method, the richter scale, was developed by charles f. Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.

What Is the Earthquake Scale Called?

The earthquake scale is called the Richter scale. It was developed in 1935 by Charles Richter, a seismologist at the California Institute of Technology.

The Richter scale is a measure of the magnitude, or intensity, of an earthquake. Magnitude is a measure of the energy released by an earthquake.

The Richter scale is logarithmic, which means that each increase of one unit represents a tenfold increase in magnitude.

For example, an earthquake with a magnitude of 5 is ten times as powerful as an earthquake with a magnitude of 4. The Richter scale is used to classify earthquakes into six categories, according to their magnitude.

The categories are: Minor: magnitude 2.02.9 Light: magnitude 3.03.9 Moderate: magnitude 4.04.9 Strong:

magnitude 5.05.9 Major: magnitude 6.06.9 Great: magnitude 7.0 or higher The Richter scale is not linear, which means that an earthquake with a magnitude of 6 is not twice as powerful as an earthquake with a magnitude of 5.

In fact, an earthquake with a magnitude of 6 is about 32 times
