Mountain in Vienna erupted, trapping relative (5,4)

I believe the answer is:

nanda devi

'mountain' is the definition.
(I've seen this before)

'vienna erupted trapping relative' is the wordplay.
'erupted' indicates an anagram (I've seen 'erupting' mean this).
'trapping' means one lot of letters goes inside another.
'relative' becomes 'dad' (dad is a kind of relative).
'vienna' with letters rearranged gives 'nanevi'.
'nanevi' placed around 'dad' is 'NANDA DEVI'.

'in' is the link.

(Another definition for nanda devi that I've seen is " mountain".)

I've seen this clue in The Hindu.
