english: Instead of belching out lava, they were belching out big, big bubbles of methane. And they were creating these volcanoes, and there were flows, not of lava, but of the mud coming out of the Earth but driven by -- I've never seen this before.
non_english: In plaats van lava bliezen ze grote bellen methaan uit. Ze vormden deze vulkanen en er waren stromen, niet van lava, maar van modder die uit de aarde komt. Ik had dit nog nooit gezien.
