Just a wild thought about built up stress at plate boundry

 Just a wild thought

 We know following things in case of Earth crust plates

1) Area of plates

2) Depth of plate 

3) hence volume of a given plate

4) Average density of a plate (Hence weight of the plate)

5) Area of contact (fault line length and depth)

6) Speed of plate (Hence kinetic energy )

Now we take out sample from Earth crust depth (maximum possible ) and test in laboratory for their compressive strength and shear strength

 Take necessary factor of safety as per engineering standard 

 With all these are we able to say that ,the given fault line is now on verge of exceeding the laboratory tested strength multiplied by factor of safety ?

  Can we able to say with certainty that the given fault line will exceed the limit of shear strength in couple of years (not exceeding  5 years ) ?

 I would like expert opinion on this
