Difference between Instability and Upheaval

INSTABILITY vs UPHEAVAL: NOUN

Unreliability attributable to being unstable
An unstable order
A state of disequilibrium (as may occur in cases of inner ear disease)
The quality or condition of being unstable.
The state of being unstable; want of stability or firmness, physical or moral; liability to fall, fail, give way, or suffer change.
Lack of determination of fixedness; inconstancy; fickleness; mutability; changeableness
The quality of being unstable.
A state that is not in equilibrium, or in which a small change has a large irreversible effect.
A lack of balance or state of disequilibrium
The quality or attribute of being unstable and irresolute

A state of violent disturbance and disorder (as in politics or social conditions generally)
A violent disturbance
Disturbance usually in protest
The process of being heaved upward.
An instance of being so heaved.
A sudden, violent disruption or upset.
A raising of a part of the earth's crust.
The act of upheaving, or the state of being upheaved; a heaving or lifting up; specifically, in geology, a disturbance of a part of the earth's crust, having as one of its results that certain areas occupy a higher position with reference to adjacent areas than they did before the disturbance took place.
The process of being heaved upward, especially the raising of part of the earth's crust
A sudden violent upset, disruption or convulsion
(geology) a rise of land to a higher elevation (as in the process of mountain building)

The graded system classifies ankle instability according to mechanism of injury, ankle instability, and degree of ligament disruption.
In some there is a clearly defined traumatic cause for the instability and the instability is unidirectional.
As we have emphasised above, legal uncertainty here also includes legal instablity, and legal instability is correlated with political instability.
The shoulder also should be examined for associated posterior instability as well as multidirectional instability.
We found that climate instability will lead to instability in geopolitics and impact American military operations around the world.
This presents a paradox, patients with cervical instability are getting surgeries that cause more instability and deformity.
Anterior instability is the most common form of glenohumeral instability and may be associated with nerve injury.
This further indicates that instability in area became major responsible factor for production instability.
The consequences of mistaking multidirectional instability for pure anterior instability are substantial.
The most common type of shoulder instability is traumatic anterior instability.
