We classifiy earthquakes by depth and type of plate boundary in which they occur. We said that several things controlled whether we had brittle or ductile failure. Temperature, Composition, Strain Rate and Confining Pressure. Remember the definition of confining pressure. If so, it must be high around 600-700 km depth.
Earthquakes release energy when they occur.
Describe in detail. How do we use seismic waves to measure earthquakes. Describe the principle behind a seismometer and how the properties of seismic waves help measure the location of an earthquake. Explain how to locate an earthquake as you did in discussion section. Explain what each of the factors in the formula mean with respect to material properties 15.
