Lo'ihi Seamount is an undersea volcano located about 22 miles off the coast of Hawaii. It is the newest addition to the Hawaiian Emperor Seamount Chain, a string of volcanoes that stretch over 3600 miles.
The Lo'ihi Seamount began forming 400 000 years ago, and is expected to peak it’s head out in about 10 000-100 000 years from now. In the meantime, it’s slowly expanding Hawaii’s land. It has also been known to cause several major Earthquakes, one of which lasted several months.
Almost like a living organism, this volcano has been growing at a constant rate. Yes it’s expanding the Hawaiian territories now, but one day it can completely drown it in a sea of molten rock and lava.
