Earthquake degree.

Intensity of an earthquake is a measure of its effect, i.e. degree of damage; for example broken windows, collapsed houses etc. produced by an earthquake at a particular place. The effect of the earthquake may cause collapsed houses at city A, broken windows at city B and no damage at city C. IntensityThis lecture will focuses on the dynamics and response to earthquakes. It will include a review of single-degree-of-freedom dynamics. An explanation of harmonic response spectra and a discussion of earthquake response spectra and inelastic response will be discussed.

Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations.An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
