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)
“Just as we are learning to value and conserve the air we breathe, the water we drink, the energy we use, we must learn to value and conserve our capacity for nurture. Otherwise, in the name of human potential we will slowly but surely erode the source of our humanity.”
—Elaine Heffner (20th century)
