Volcano in Red Isle

So I was watching the Y2 teaser and I noticed something. There is quite a high mountain in the background of the Frigate scene. I went in game and took a picture of Sainte Anne from the same angle, and you can clearly see that the mountain ridges are different in the teaser compared to how they are in game. (Check the orange lines in the picture below)

Maybe that's just a render distance difference, but later in the teaser there's also a scene that shows a volcano with some african buildings around. So I suspect this is a new volcano that will erupt on the mountains behind Vorona Falls in addition to the one in Africa. Maybe there will be some sort of event tied to it. What do you think?
