Yep, you are right.
But I was not sure myself where to put my pictures from Hawaii and I asked @czechglobalhosts, the organizer. His answer was North America - see the exchange here: https://steemit.com/travel/@libork/re-czechglobalhosts-7-world-s-continents-photo-challenge-tuesday-of-antarctica-and-world-s-oceans-week-33-the-absolute-winner-takes-200-sbd-20180508t090833378z
I guess that this is what matters here...
Ok cool! Their contest, their rules... but thanks for this feedback and good to know you heard it straight from @czechglobalhosts!
PS. Cool video, leaves some important questions. I'll repost this link here for others to enjoy...
It (Hawaii) is in the middle of the Pacific plate, so I vote for Oceania or Pacific Plate. Hahaha which are not options...
PSS. Nevertheless your photo is awesome and needs a home and would love to visit that place sometime way up high above the Pacific...
