Seismic scale range
The Richter scale measures the magnitude of an earthquake's largest jolt of energy. This is determined by using the height of the waves recorded on a seismograph. The Richter scale is logarithmic. The magnitudes jump from one level to the next. The height of the largest wave increases 10 times with each level.So, for example, a magnitude 2 earthquake is 31 times more powerful than a magnitude 1 earthquake. The moment magnitude scale is often referred to by the name of its predecessor, the Richter Scale. Measurements on the Modified Mercalli Intensity (MMI) scale range from I to XII and are based solely on damage assessment and eyewitness accounts. To find the mean, add all the numbers together then divide by the number of numbers. Eg 6 + 3 + 100 + 3 + 13 = 125 ÷ 5 = 25. The mean is 25. The mean is not always a whole number.
