Radiated Seismic Energy
Potential energy is stored in the crust in the form of built-up stress. During an earthquake, this stored energy is transformed and results in
- cracks and deformation in rocks
- heat
- radiated seismic energy .
The seismic moment is a measure of the total amount of energy that is transformed during an earthquake. Only a small fraction of the seismic moment is converted into radiated seismic energy, which is what seismographs register. Using the estimate
Choy and Boatwright defined in 1995 the energy magnitude

Famous quotes containing the words seismic and/or energy:
“Most near, most dear, most loved and most far,
Under the window where I often found her
Sitting as huge as Asia, seismic with laughter,”
—George Barker (b. 1913)
“Long before Einstein told us that matter is energy, Machiavelli and Hobbes and other modern political philosophers defined man as a lump of matter whose most politically relevant attribute is a form of energy called “self-interestedness.” This was not a portrait of man “warts and all.” It was all wart.”
—George F. Will (b. 1941)
