Web2 hours ago · The shake table will simulate earthquake motions recorded during prior earthquakes covering a range of earthquake magnitudes on the Richter scale, from magnitude 4 to magnitude 8, including various iterations of the 6.7 magnitude Northridge earthquake which struck Los Angeles in 1994 . This will be done by accelerating the table … WebWhat is the Richter Scale The Richter magnitude scale (often shortened to Richter scale) is the most common standard of measurement for earthquakes. It was invented in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.
