I believe it's related to the heat from Earth's interior, which in turn is mainly due to radioactive decay.
Roughly 32 times more energy is released in a Magnitude 6 earthquake than in a Mag.5 quake.
The earthquake magnitude is a measure of the energy released during an earthquake. The scale is logarithmic, such that a magnitude of 6.0 releases about 32 times more energy than a magnitude 5.0 earthquake, and in turn more than 900 times more energy than a magnitude 4.0 earthquake.
In terms of energy output an earthquake is stronger.
Seismic energy increases by a factor of about 31.6 for each increase of magnitude, so a magnitude 3 earthquake has 31.6 times more energy released than a magnitude 2 earthquake.
Energy is stored in the form of stress as tectonic plates move and become locked against each other. As the plates continue to move and the stress builds up, the stored energy increases until it reaches a point where the rocks break and release the energy in the form of seismic waves, causing an earthquake.
The measure of energy released by an earthquake depends on its magnitude. If its a high magnitude earthquake, there is a lot of energy. If there is a low magnitude, then there is little energy.
The energy released during a 7.0 earthquake is equivalent to about 32 million pounds of TNT, which is a massive amount of energy. The destruction caused by such an earthquake can be widespread and devastating.
How to make Mountain: Mountain: Earth + Earthquake = Mountain Earth: STARTER Earthquake: Earth + Energy = Earthquake Earth: STARTER Energy: Fire + Air = Energy Fire: STARTER Air: STARTER
The origin of an earthquake is called the hypocenter or focus. This is the point within the Earth where the earthquake begins and energy is released.
Vibration
yes
The energy of an earthquake is stored as elastic strain energy in the Earth's crust along the fault line prior to the earthquake. This energy is released when the stress on the fault exceeds the strength of the rocks, causing them to break and the energy to be radiated as seismic waves.
