    The Richter Scale gives a mathematical model for the magnitude of an earthquake in terms of the ratio of the amplitude of an earthquake wave (also known as the intensity of an earthquake) to the amplitude of the smallest detectable wave. If we denote the magnitude of the earthquake by R, the intensity (also known as the amplitude of the earthquake wave) of the earthquake by A, and the amplitude of the smallest detectable wave by S, then we can...

    Earthquake Lab: Locating the Epicenter, Determining the Magnitude, and Calculating the Time of Earthquake The goal of this lab is to learn how seismograms are used to locate the epicenter of earthquakes, determine earthquake magnitudes, and to calculate the origin time of earthquakes. A seismogram measures the amount of shaking caused by earthquake waves. The seismogram first records the arrival of P-Waves (Primary), followed by the arrival of the S-Waves (Secondary). The S-P interval is the time difference between the...
