What is Loihi and why is it significant?
For the computer chip, see Loihi. Lōʻihi Seamount (also known as Lōihi) is an active submarine volcano about 22 mi (35 km) off the southeast coast of the island of Hawaii. At its summit, Lōʻihi Seamount stands more than 10,000 ft (3,000 m) above the seafloor, making it taller than Mount St.
What is Loihi and what seafloor feature does it originate from?
This sea floor was itself created some 6000 km away on the undersea volcanic mountain chain known as the East Pacific Rise. It has slowly moved north-westward to the present location of the Hawaiian Hotspot. It was revealed that Loihi was a young, active volcano, rather than an old dead seamount from a bygone aeon.
How do we know what Loihi looks like?
Loihi (which is the Hawaiian word for “long”) has an elongated morphology dominated by two curving rift zones extending north and south of the summit. The summit region contains a caldera about 3 x 4 km wide and is dotted with numerous lava cones, the highest of which is about 975 m below the sea surface.
How long will it take Loihi to surface?
It’s not known when Lō’ihi will breach sea level. We can speculate that with a growth rate of 5 m (16.4 ft) per 1000 years it will take as much as 200,000 years to reach the ocean surface. It all depends upon the eruption rate.
What direction is the plate moving to form loihi?
Near Hawaii, the age progression from island to island can be used to calculate the motion of the Pacific Oceanic plate toward the northwest. The youngest seamount of the Hawaiian chain is Loihi, which presently is erupting from its summit at a depth of 1000 meters.
Where are seamounts located?
Seamounts are commonly found near the boundaries of Earth’s tectonic plates and mid-plate near hotspots. At mid-ocean ridges, plates are spreading apart and magma rises to fill the gaps.
What does Loihi mean in Hawaiian?
Loihi, pronounced low-EE-Hee and meaning “long” or “tall” in Hawaiian, juts like a spur from the side of the “Big Island” of Hawaii, about 20 miles off the southern shore.
