The Richter Scale Problems 133 and 134 on the next page use the following discussion: The Richter Scale is one way of converting seismographic readings into numbers that provide an easy reference for measuring the magnitude M of an earthquake. All earthquakes are compared to a zero-level earthquake whose seismographic reading measures 0.001 millimeter at a distance of 100 kilometers from the epicenter. An earthquake whose seismographic reading measures x millimeters has magnitude M ( x ) , given by M ( x ) = log ( x x 0 ) where x 0 = 10 − 3 is the reading of a zero-level earthquake the same distance from its epicenter. In Problems 133 and 134, determine the magnitude of each earthquake. Magnitude of an Earthquake San Francisco in 1906: seismographic reading οf 50,119 millimeters 100 kilometers from the center.
