The Richter scale [1] ( / ˈrɪktər / ), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". [3]

Magnitude is a measure of the amplitude (height) of the seismic waves an earthquake’s source produces as recorded by seismographs. Seismologist Charles F. Richter created an earthquake magnitude scale using the logarithm of the largest seismic wave’s amplitude to base 10.The magnitude of an earthquake is a measure of the energy it releases. This means that it doesn't matter that the earthquake might not "feel" as strong farther away from its source; the magnitude just depends on the earthquake's total energy. The more energy released by an earthquake, the higher the magnitude.

A 7.0 magnitude earthquake can split a fault area measuring approximately 1000 kilometers per square which is almost 20 kilometers wide and 50 kilometers long. The Significance of Depth in Determining the Magnitude of Earthquake. Depth is a critical factor that has an impact on the magnitude of earthquakes.

While the death toll and destruction of the recent earthquake in Turkey and Syria dominate the news, many wonder how strong the quake was and what the scale used to measure earthquakes means. The Richter scale is a tool used to measure the magnitude of earthquakes. Developed in the 1930s by seismologist Charles Richter, …The United States Geological Survey (USGS) initially reported the quake as being of magnitude 6.4 at a depth of 10 kilometers before revising it down to 6.3 magnitude. Officials have been urging ...For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.Earthquake Magnitude. The magnitude is the most often cited measure of an earthquake's size, but it is not the only measure, and in fact, there are different types of earthquake magnitude. Early estimates of earthquake size were based on non-instrumental measures of the earthquakes effects. ... Also, measures of earthquake …Magnitude is the most commonly used measure to describe the overall strength or size of an earthquake. The magnitude of an earthquake is expressed in decimal fractions and whole numbers. For example, a magnitude of 5.3 is considered a moderate earthquake whereas a magnitude of 6.3 is a strong earthquake.

Magnitude means how big or strong something is. Higher numbers mean stronger earthquakes. The scale is a little bit tricky because for each number you go up in the scale, the strength of the earthquake is 10 times stronger. For example, a 5.0 earthquake is about 10 times stronger than a 4.0 earthquake, and 100 times stronger …A 7.6-magnitude earthquake shook the Pacific coast of central Mexico Monday, killing at least one person, according to the U.S. Geological Survey.
