'european capital's' is the definition.
(capital of Slovakia)

'terror is linked to volcanic emissions' is the wordplay.
'terror' becomes 'brat' (both can mean a misbehaving child).
'linked to' means one lot of letters go next to another.
'volcanic emissions' becomes 'lava' (I can't justify this - if you can you should give a lot more credence to this answer).
'brat'+'is'+'lava'='BRATISLAVA'

Can you help me to learn more?
