Well, I was thinking about this earlier...
I saw the thread about the upcoming Supermoon, and how the moon is currently 90% bigger than usual or something like that. Well, since the moon controls tides and waves, isn't it quite possible that since this "Supermoon" is near and is already taking effect, that it could possibly change tides or something like that? Cause tsunamis? I know tsunamis are caused by underground earthquakes and cracks in the crust but... What do you think?
