| Comments: | Believe this was Giant based on the video replay of heavy steam in the right place in the strong wind and it lasting 1-1.5h. Could have had Mastiff at 1233 as there's a strong steam cloud visible before the really thick and taller steam at 1235. Giant had been reported wc 2 days earlier but suspect that was Grotto. This eruption confirmed by electronic data. |
