In quakes, most err badly (7)

I believe the answer is:

tremors

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

'in quakes' is the definition.
'tremors' can be an answer for 'quakes' ('tremor' can be a synonym of 'quake'). I'm unsure of the 'in' bit.

'most err badly' is the wordplay.
'badly' indicates an anagram.
'most'+'err'='mosterr'
'mosterr' is an anagram of 'TREMORS'.

Can you help me to learn more?

(Other definitions for tremors that I've seen before include "Small earthquakes" , "Err most (anag.)" , "Vibrations" , "Quivering movements" , "Quakings" .)
