Faults? No. Movement on a fault can be a very slow (and I mean V-E-R-Y slow...) process, and may result in land either being slowly lifted or slowly subsiding.
There are thousands of faults in continental crust, but only a few plate boundaries. It's usually (but now always) at plate boundaries that destructive earthquakes occur

Of course not. There is a pyramid-like (I suppose logarithmic or exponential would be more accurate) distribution of earthquake intensities associated with movement along a given fault, with lots of small, and frequently not even noticible (except by instruments) quakes, a lot fewer moderate quakes, and rare large quakes.

Basically, the small slippages happen all the time, the moderate ones happen once in a while, and the big jumps are rare (thank god or whatever you wish to thank).

tsunami waves are formed from earthquakes that are reason by utilising the moving of tectonic plates under the earths crust or by utilising a huge adequate landslide. that's even concept that an enormous adequate bomb, displacing billions of gallons of water in a mater of seconds ought to reason a devestating tsunami Tsunamis could be undesirable and likewise good for the ecosystem. An occasion of it being undesirable is that it has the aptitude to destroy animals that are area of the eco gadget . All animals are interior the circle of existence and if one is eradicated, it could have a soft or maybe huge consequence on some species one way or yet another. a reliable occasion of a tsunami is the cleansing of earth. Ecosystems have certainly been created as a consequence of tsunamis. From billions of gallons of water being trapped inland. even nevertheless human beings lives are invaluable, human beings even have the potential to destroy. i'm a company believer in international warming and a tsunami in any important commercial country ought to sluggish the warming of the earth for years. An occasion, which i'm hoping by no potential comes authentic is what if a important tsunami hit long island which places out pollutants noticeably. a tsunami could very much shrink down the fossile gas use and smog output.

Slip on any fault can be undetectable (aseismic), in frequent small to very small increments, fewer moderate increments, or rare very large increments. The type of slip depends on the frictional resistance to sliding on the fault, and this depends on a number of factors like the grain size of the rocks in the fault, the amount of water circulating in the fault plane, and the type of fault (extensional (stretching) or compressional (squeezing) - the latter tend to be the most severe.)

Faults can move via 'fault creep' where displacement accumulates without episodic quaking. However - faults often become locked and then this pressure will be released in a quake of some magnitude.

There are a lot of minor quakes, say 5.0 or less that cause little of no harm. Some are not even felt.

it depends on a variety of factors. the amount of movement, the velocity of movement, the direction of movement, the type or types of soil involved. the type and quality of structures involved, but i suppose the main factor is the overall magnitude. look up the the ricther scale.
