The Richter scale The most popular technique to measure earthquakes is the Richter scale. This scale was invented by Charles Richter and Beno Gutenberg in 1935. Often you hear that the Richter scale goes from <2 (slight tremor) to ten (global disaster), but actually the scale is open at the top. However the characteristics of the earth `s crust make an earthquake over 9,5 almost impossible, it would discharge before the value was exceeded. Heavy earthquakes are not measured by the Richter scale because when they reach a value over 6,5 the scale loses their accuracy. You often hear in the news or read in the newspaper that the earthquake had a certain value according the Richter scale, but that isn`t true. Nowadays earthquakes are measured according the Moment magnitude scale. The Moment magnitude scale has a limit by 10,6. Scientists assume that at this value the earth crust would collapse. The heaviest measured earthquake happened on the 22. May in one thousand, nine hundred and sixty in Chile. It reached a value of about 9,5 on the Moment magnitude scale. This earthquake costed one thousand, six hundred and fifty-five people their life. Many people were able to save their lives because there were a lot of slighter tremors before. Thereby many were able to save themselves by leaving there houses. Otherwise the number of casualties would been much higher. The earthquake was followed by a huge tsunami. His almost twelve meter high waves devastated the city of Puerto Saavedra. Also the coast of Hawaii was reached by 10 meter high waves, and one day later reached a 5,5 meter high wave the coast of Japan.
