The Richter and Marcalli scales

The Richter and Marcalli scale both measure how strong and how damaging earthquakes are. There are also some different things about them to.
The Richter scale graph is different the marcalli scale because it uses seismograms to record on a graph chart. On the graph it lines get bigger as the earthquake gets stronger. The scale assigns a single number to quantify the amount of seismic energy released by an earthquake. On a Mercalli scale it shows it by color. As the color gets warmer the intensity of the earthquake gets stronger. It quantifies the effects of the earthquake on earth’s surface, human objects of nature, and man made structures. The low degrees of the mm scales generally deal with the manner in which the earthquake is felt by people. The Richter scale was developed in 1935 by Charles Richter with Beno Guten Berg. The Marcalli scale was created by and Italian volcanologist Adolfo Cancani in 1945. The Richter scale can also record how many earthquakes there are in days, months, and even years. The Richter and Marcalli scale helps scientist figure out how much damage an earthquake can make. Even though they both help figure out how much damage earthquakes can make they are still different from the graphs they use and the technology. HLB5
