Tongariro
85 million of years ago, while the dinosaurs roamed the Earth, the Pacific seafloor consisted of many plates. Due to plate tectonic processes of seafloor spreading, drifting and subduction most of them were melted beneath the circum-pacific Ring of Fire. A single gigantic pacific plate formed. Its active borders create deep ocean trenches and the famous volcanoes of the Ring of Fire. Notorious killer-volcanoes around the Pacific. One of them is Mt. Tongariro of New Zealand’s North Island. What we see today is just a snap shot of the geological processes within the Ring of Fire. New Zealand’s geology is complicated. Geologically speaking New Zealand is a hybrid composed of continental granite and island creating volcanic rock. The collision zone of the Pacific and Indo-Australian ocean plates runs through the middle of New Zealand, exactly beneath volcanoes of the Tongariro chain. The geologically young and active volcanic landscape is characterized by bilious green crater lakes.
