Volcanic outpouring (4)

Ross

I believe the answer is:

lava

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

This is the entire clue.

(Other definitions for lava that I've seen before include "Unstoppable red tide" , "Discharge from volcano" , "Volcano output" , "Volcanic emanation" , "Hot flowing rock" .)

I've seen this clue in The Star Tribune.
