A.T. Robertson Commentary Luke 8:33

"And the demons came out from the man, and entered into the swine: and the herd rushed down the steep into the lake, and were drowned." — Luke 8:33 (ASV)

Rushed down the steep (ωρμησεν κατα του κρημνου). Ablative with κατα as in Mr 5:13; Matthew 8:32 and the same vivid verb in each account, to hurl impetuously, to rush.

Were choked (απεπνιγη). Second aorist (constative) passive indicative third singular (collective singular) where Mr 5:13 has the picturesque imperfect επνιγοντο.
