Canary Islands Eruption Could Create New Land 93
wanzeo writes "An undersea volcano is erupting off the coast of the Canary Islands, bringing the potential for new land formation. The lava peak has grown 100 meters from the ocean floor, and is now just 70 meters from the surface. It has been seen ejecting rocks from the sea and producing jets of water 20 meters high. Increasing seismic activity has been monitored since July, an indication that magma is rapidly moving toward the surface. Local residents have been evacuated because of the potential danger from falling rocks or violent steam explosions if the lava gets too close."

Funny enough, that already happened. In 1811 a similar underwater eruption near the Azores archipelago [wikipedia.org] caught the eye of a captain of a HMS Sabrina, a British warship. After noticing that the underwater volcanic eruption formed a small island, HMS Sabrina's captain decided to claim it for Britain through the cunning use of flags [youtube.com], in essence stealing portuguese land from under them and thumbing the nose at the Portuguese crown, which also happened to be an allied state. They named the new island Sabrina island [wikipedia.org] and proceeded to have a diplomatic row over this small episode. In the end the joke was on Britain, as the newly formed island crumbled into the sea.

While this island lies clearly within the territorial limits of the Canary Islands (Spain) the question of Lo'ihi [usgs.gov] is not so certain.
Lo'ihi is still some distance (~969 meters) below the surface, but growing steadily, and when it breaks the surface it will be 30km from the Big Island in Hawaii, which is well outside the US claimed 22km territorial limit [wikipedia.org]. The chances of the US allowing anyone else to claim it are slim to none, but the precedent set in 1811 would pretty much assure the US will have boots on the ground before anyone else gets a chance.
While Hawaiian volcanoes are typically slow growing, Lo'ihi is thought to be fed by the same lava plume feeding the Mauna Loa and Kilauea volcanoes. Should the plume find easier going to the east, Lo'ihi could draw upon pretty vast resources and grow much faster.
Re: (Score:3)
Even if it DOES grow much faster, you're still talking faster in Geological terms.
It will be thousands and more likely tens of thousands of years before Lo'ihi breaks the surface.
Also (was on the big island not 2 weeks ago) while visiting I the USGS site in Volcanoes National park, the prevailing belief is that long term Lo'ihi will merge with the big island as another peak the way Mauna Loa and Mauna Kea already have.

Not so far from Cumbre Vieja (Score:5, Interesting)
The eruption is near the island of El Hierro, about 90 km south of the volcano Cumbre Vieja on La Palma. A few years ago Cumbre Vieja was in the news as a possible source of a mega-tsunami that would devastate the west coasts of Africa and Europe and the east coast of North America. Wikipedia has the story: http://en.wikipedia.org/wiki/Cumbre_Vieja [wikipedia.org]. The problem is that the volcano is unstable, and it could collapse and dump 500 km^3 of rock into the ocean.
Hopefully 90 km is far enough away not to bother it...

I believe that answer is actually much greater than zero (possibly 1.00), depending upon the the allowed timescale. Coral atolls are formed on top of old volcanices.
From the last the last of the following links:
"In 1842 Darwin explained the creation of coral atolls in the southern Pacific Ocean based upon observations made during a five-year voyage aboard the HMS Beagle from 1831 to 1836. Accepted as basically correct, his explanation involved considering that several tropical island types—from high volcanic island, through barrier reef island, to atoll—represented a sequence of gradual subsidence of what started as an oceanic volcano. He reasoned that a fringing coral reef surrounding a volcanic island in the tropical sea will grow upwards as the island subsides (sinks), becoming an "almost atoll", or barrier reef island, as typified by an island such as Aitutaki in the Cook Islands, Bora Bora and others in the Society Islands. The fringing reef becomes a barrier reef for the reason that the outer part of the reef maintains itself near sea level through biotic growth, while the inner part of the reef falls behind, becoming a lagoon because conditions are less favorable for the coral and calcareous algae responsible for most reef growth. In time, subsidence carries the old volcano below the ocean surface and the barrier reef remains. At this point, the island has become an atoll."

As a geologist, I'd say that the answer is not so simple. It's like breathing.

Makes me wonder if it might be possible to exploit weak spots in the earth crust to create islands artificially. Second I wonder how safe it would be.
But suppose instead of destabilizing the crust you instead you just drilled down to the magma and pumped it out? If you could build a piping system that
could pump magma under cold ocean without clogging up the pipe that is... Forget about super conductors... what about super insulators at high temperatures?
Maybe in a couple hundred years... Should be possible to create the equivalent land mass of Hawaii in a few different places in the worlds or to at least double or triple their the land masses of existing islands within a ten year controlled period.
And for places like Yellowstone maybe even create a few mountains nearby to relieve the pressure.
