Earthquakes 4.5 or higher on the Richter scale can be measured all over the world.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 ...Magnitude is the measure of the energy released by an earthquake.
