Can't say I've ever seen or touched a plate or fault.
I happen to have both seen and touched a fault as well as been touched by a fault.
I was living in California during the San Fernando Valley Earthquake back in 1971.
We woke early in the morning when our dogs started barking. Then things began moving. It was pretty obvious that it was an earthquake and not all that small a one either. My wife and I tried to get out of bed but the damn bed kept moving under us. Doors and drawers opened and closed, pictures fell off the wall and we could hear the sounds of breaking glass coming from the kitchen.
It was barely light out, the street lights on the Ventura hills across the harbour were still lit, and we could see the lights swaying behind the stationary masts of sailboats moored in the canal.
Later in the day we were inspecting damage. There was a crack in the patio about two feet wide and deeper than I could reach with an extended broom. The garage on the building had been shoved up almost three feet so that the deck on the roof of the garage was now midway up the sliding glass door that opened onto it.
Based on personal experience, I can attest that Plate Techtonics is NOT just a theory, and that there most certainly are forces capable of raising mountains. In this particular case, by about 2 meters in a matter of seconds.

Re: Rate of growth?
It was not amazing, it was awsome. Quite literally.
Here is a link to some data on it. I am perfectly willing to accept just about any height change from the smallest to the largest figures. The absolute amount is really not important.
The key fact is that plate tectonics happen, earthquakes happen and it is absolutely true that such movements can raise what was once at sea level to tens of thousands of feet above sea level.
One big differnce between the San Fernando quake and Northridge was that the San Fernando Quake was a Thrust type, it actually broke the surface, while Northridge was a Blind Thrust. The San Fernado Quake would produce escarpments while the Northridge would produce the folded and bent strata.

Re: Rate of growth?
Many people are suprised. But stop and think for a second.
The San Fernando Earthquake happend slightly over 5.2 miles beneath the surface yet broke the surface along a stretch of over 12 miles in length. Compare that to Mount Everest which is 5.4 miles high. So one rather moderate to severe earthquake moved a block of continent equal to the height of Mount Everest.
