What's Happening to the Water?

No one has ever seen an actual eruption like this. And you wouldn't. No one knows how large the bubbles coming off the methane deposit would be, but- In theory. But yeah, but the scientists who, well, pump your break. They have floating on the surface. If it is exactly above the bubble, then it's safe. But if it's far enough away, safe, it's where it's toward the edge that it just sinks in. The bubble sort of swallows it for lack of a better word, which to me is more frightening than an explosion.
