whats the origin of the term ' catastrophysics'.?

Answer 1

The physics of catastrophe. The forces behind building collapse, bridge failure, and even natural disasters would fall under this category. I don't know the origin of the individual words, (physics is the study of physical forces, but catastrophe has me stumped). The word catastrophysics is simply a combination of the two words.

Answer 2

I think you mean catastrophic
1. Of, relating to, or involving a catastrophe.
2. Involving or resulting in substantial, often ruinous medical expense: a catastrophic illness.
OR MAYBE YOU MEAN:
catastrophism
n.
1. Geology The doctrine that major changes in the earth's crust result from catastrophes rather than evolutionary processes.
2. The prediction or expectation of cataclysmic upheaval, as in political or social developments.

Here's the origin:
Greek katastrophē, an overturning, ruin, conclusion, from katastrephein, to ruin, undo : kata-, cata- + strephein, to turn; see streb(h)- in Indo-European roots.]
