# 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
