1.1 The foundation of seismology: seismograms. Seismograms serve as the foundation for global seismology. An example seismic recording is shown in Fig. 1.1. Three orthogonal components of motion (up–down, north–south, and east–west) record the total (vector) ground displacement as a function of time. The example data were recorded at ... The critical angle is the angle of incidence to which the angle of refraction is equivalent to 90 °. When light enters a denser media from such a comparably rarer medium, the orientation of light changes as well as the light beam bending towards the normal. Absolute internal reflection is the complete reflection of such a light beam from the ...Importance.

You can see their catalog of "earthquake solutions" or view a map with focal mechanisms for recent events.What is a seismograph. A seismograph, or seismometer, is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions. They travel through the interior of the Earth and can be measured with sensitive detectors called seismographs.
