Rush, causing damage (4)
I believe the answer is:
tear
I believe this is a double definition.
'rush' is the first definition.
(tearing is a kind of rushing)
'damage' is the second definition.
(thesaurus)
'causing' is the link.
(Other definitions for tear that I've seen before include "Shred" , "Lacerate - sign of sorrow" , "A rip goes on a binge?" , "A rip or cut" , "Rip; salty drop" .)
