Автор: An island that looks like a phoenix arose off the coast of Japan. It grew from the volcanic ash of the Ring of Fire, off the coast of Japan’s Ogasawara Islands (Bonin).
According to volcanologist Setsuya Nakada of the University of Tokyo, the underwater volcanic eruption that formed the island began as a “vertical jet” of solidified magma that shot out high above the waves. Sciencealert writes about it.
After that, the eruption was sustained by continuous flashes. This debris fell back into the ocean as lava mixed with a low-density, porous material called pumice. The rock embankment grew and became high enough to peek out from the depths.
The eruption continues even now, although it seems to have reached its peak and is subsiding somewhat.
In the near future, the new massif of land may increase slightly. But pumice that is not cemented by lava flows will be eroded. Therefore, part of the island may shrink over time.
