Cataclysmic becoming hater after this? (5-10)

I believe the answer is:

earth-shattering

I'm a little stuck... Click here to teach me more about this clue!

'cataclysmic' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?

'hater after this?' is the wordplay.
I cannot really understand how this works, but
an anagram of 'hater' is 'earth' which is located in the answer.
The remaining letters 'shattering' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'becoming' acts as a link.

Can you help me to learn more?
