Ring of Fire volcanic eruptions of the last 11,700 years occurred at volcanoes in the Ring of Fire. The Ring of Fire is a direct result of plate tectonics: the movement and collisions of lithospheric plates, especially subduction in the northern portion. The southern portion is more complex, with a number of smaller tectonic plates in collision with the Pacific plate from the Mariana Islands, the Philippines, Bougainville, Tonga, and New Zealand. The presence of a belt of volcanic activity surrounding the Pacific Ocean was observed in the 19th century. "They [the Japanese Islands] are in the line of that immense circle of
Ring of Fire (Northern Ontario) Action Plan noted that First Nations were interested in potential legacy impacts of Ring of Fire infrastructure, such as all-weather roads, links to the power grid and high-speed broadband Internet.
