(2) where PGA is the peak ground acceleration (cm/s 2) and MMI is the level of macroseismic intensity in terms of MMI scale. 4.Measuring earthquakes. Scientists use two values to describe the size of an earthquake – magnitude and intensity. Magnitude. The magnitude of an earthquake is a measure of the total amount of energy released by the ground movement at its source. It is commonly determined by analysing the shaking recorded on several seismographs. Earthquake magnitude is a quantitative, mathematical calculation to measure the energy released at the source of an earthquake. On the other hand, earthquake intensity is the qualitative measurement of the strength of shaking produced by an earthquake.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]Enter the two magnitudes you want to compare – for our example, these are 5.8 and 7.1. We find out that a magnitude of 7.1 is 20 times bigger (on a seismogram, in terms of amplitudes) and ~89 times stronger (in terms of energy release) than a 5.8 magnitude. Remember that for each unit increase in magnitude:10-15. 8.0 or greater. Great earthquake. Can totally destroy communities near the epicenter. One every year or two. Modified Mercalli Intensity Scale. Top. Magnitude scales can be used to describe earthquakes so small that they are expressed in negative numbers. The scale also has no upper limit.Check your chimney or roof for loose tiles and bricks that could fall in an earthquake. Repair loose tiles or bricks, as needed.
