Slope movements are commonly preceded by a decrease in effective stress because there is a direct correlation between effective stress and the strength of a frictional material like soil, whereby as the effective stress decreases, the normal stress on any potential shear surface within the material also decreases. This in turn leads to a reduction in the shear strength of said surface. If this reduces to such an extent that the shear stress on the surface exceeds the frictional shear strength, movement can occur.
Further to this, slopes composed of fine grained clay soils will undergo shrink and swell cycles as effective stress changes occur which can lead to strain softening behaviour and progressive failure.
For more information see the related link.
In particular review the equation in section 3.4 where frictional strength on a theoretical slip surface is shown to be dependent on the total normal stress (sigma n) acting on the surface minus the pore water pressure (u) or in other words the strength is directly proportional to the normal effective stress).

No historians have written about the era that preceded the ancient era.
No. It is commonly preceded by a preposition because it is the objective form of "who." You could say "who called whom" without using a preposition.
It is the United States Dollar. Dollar quantities are commonly preceded with a $ mark. Example: $100.00
An Italian overture is generally divided into three-movements. Generally, the latter movements have a quick tempo whereas the middle movement has a slow tempo. So it might go something like a prelude preceded by an adagio movement and then an allegro piece.Or...fast-slow-fast
Herbert Hoover preceded Franklin Roosevelt.
The plural for pulley is pulleys. The rule for making nouns ending with 'y' plural is: If the 'y' is preceded by a vowel, add 's'. If the 'y' is preceded by a consonant, drop the 'y' and add 'ies'.

You would say "...is preceded..." if you note that fact at the person's time of death. "Was preceded" is how the obituary would be worded because it was written after the person's death. Both deaths would have happened in the past.
