Volcano here, blowing the front off public vehicle (6)
I believe the answer is:
erebus
'volcano here' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'blowing the front off public vehicle' is the wordplay.
'blowing the front off' becomes 'ere' (I can't justify this - if you can you should give a lot more credence to this answer).
'public vehicle' becomes 'bus' (I've seen this before).
'ere'+'bus'='EREBUS'
Can you help me to learn more?
(Other definitions for erebus that I've seen before include "Dark and gloomy cavern between earth and Hades." , "In place of darkness" , "Sure, be in the underworld" , "Greek god of darkness, son of Chaos" , "Antarctic volcano; region between earth and Hades" .)
