Sudden applause in Oval's erupted (5)

Ross

I believe the answer is:

salvo

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

'sudden applause' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'oval's erupted' is the wordplay.
'erupted' indicates an anagram (I've seen 'erupts' mean this).
'ovals' anagrammed gives 'SALVO'.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for salvo that I've seen before include "Discharge of weapons in unison" , "What comes across" , "Unusual excuse" , "Outburst, as of applause" , "A number of shots" .)
