The first earthquake was big - it registered as 7.8, classified as "major" on the official magnitude scale. It broke along about 100km (62 miles) of fault line, causing serious damage to buildings ...The Richter scale is a base-10 logarithmic scale, meaning that each order of magnitude is 10 times more intensive than the last one. In other words, a two is 10 times more intense than a one and a three is 100 times greater. In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake ...I. Felt by very few people; barely noticeable. II. Felt by a few people, especially on upper floors. III. Noticeable indoors, especially on upper floors, but may not be recognized as an earthquake. IV. Felt by many indoors, few outdoors. May feel like heavy truck passing by.Magnitudes are based on a logarithmic scale (base 10). What this means is that for each whole number you go up on the magnitude scale, the amplitude of the ground motion recorded by a seismograph goes up ten times. Using this scale, a magnitude 5 earthquake would result in ten times the level of ground shaking as a magnitude 4 earthquake (and ... The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations. This magnitude scale was referred to as ML, with the L standing for local. We know an earthquake is severe when it has a high magnitude number. The 1985 quake that devastated Mexico City was an 8.

Magnitude is ranked through 10, with each whole-number increase equal to 32 times more energy released.The Richter scale provides a measure of the magnitude of an earthquake. In fact, the largest Richter number M ever recorded for an earthquake was 8.9 from the 1933 earthquake in Japan. The following formula shows a relationship between the amount of energy released and the Richter number. M=2/3 log E/ 0.007 where E is measured in kilowatt-hours.The Richter Scale. From 1935 until 1970, the earthquake magnitude scale was the Richter scale, a mathematical formula invented by Caltech seismologist Charles Richter to compare quake sizes.
