In areas of high temperature and high pressure
No. Volcanic eruptions can build mountains and form new land. Many occur in remote areas where there is not much to destroy.
No they can occur at anytime.
Certainly, minor rumbles occured without any damage in Washington Dc recently. often there are seismic shakes in areas sparsely populated that are only traced on instruments and no damage, let alone deaths, occur.
No. Tsunamis can also occur as a result of landslides, volcanic eruptions, meteor impacts, and underwater explosions.
Not everyone, no. Earthquakes happen in certain areas and only those areas will feel it. Of course it depends on how strong the earthquake is.
Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.
No, because the highest amount of energy needed in a nuclear fusion is 40,000,000 K, which is only known to occur on the sun.
The rest of the sun is too cold and too low pressure.
Nuclear fusion only releases energy when elements lighter than iron are involved. This is because elements lighter than iron release energy due to the process of fusion, while elements heavier than iron require energy to be input for fusion to occur.
Nuclear fusion is used only in experimental installations.
The only place in which nuclear FUSION takes place is in stars (the sun included), and in the detonation of a hyndrogen bomb. If you are asking about nuclear FISSION (an entirely different process), restate the question.
Never, only fusion
Up to now only in H-bombs. Experiments in fusion are on going though.
The only place in the universe where nuclear fusion can occur on its own is in the interior of stars. After closely observing nature, and adapting its laws to fulfill human requirements, our advanced civilization has succeeded in creating nuclear fusion at will, on a small scale. Unfortunately, the only useful application successfully developed so far with our superior intellect is the construction of nuclear bombs and weapons.
No, a fission reaction is not necessary to trigger a fusion reaction, but for us on earth, it is. In the field of nuclear weapons, a fission bomb is needed to create the heat necessary to set off a fusion weapon. We have to use fission, or, rather, the energy created by that, to initiate the fusion reaction. It might be possible to use a high power source, like a laser, on a small amount of material to get fusion to occur. But we are still experimenting with this in the Tokamak, and it's far from being a done deal. Stars are, in general, massive nuclear fusion reactors. Their constant consumption of fuel powering their high rate of fusion creates a massive amount of energy, and the stars' huge gravity keeps this process from blowing the whole thing apart. No fission is needed to sustain this reaction.
the only planet that is known to make nuclear power at this point is earth.
In all stars, the fusion only occurs in the inner core.
