Japanese volcanic island swallows neighbor
by Brooks Hays
Tokyo (UPI) Apr 7, 2013

An imager on NASA's Earth Observing 1 satellite captured this Dec. 8 picture of the new volcanic island, Niijima, sitting next to another volcanic island called Nishino-shima. Stirred-up sediment lightens up the waters around Niijima, and the white puffs seen above the baby island and heading out to sea are thought to be clouds of steam and other volcanic gases.

Niijima island is relatively new, born just last year, but it has already become an geological aggressor.

Last November, the volcano first broke through the ocean's surface, becoming Japan's latest piece of territory in the "Ring of Fire" -- a string of heightened seismic and volcanic activity in the Pacific that stretches from the coast of Chile north to Alaska and Siberia and then circles back down past Japan and the Philippines toward New Zealand.

Now, NASA's Earth Observatory has captured evidence of expansion: the young island has continued to erupt, growing in size, and its lava recently joined with its neighbor, claiming the remnants of a 40-year-old volcanic island as its own.

The two islands -- now one -- lie amongst the churn of the Pacific some 600 miles south of Tokyo. They're -- it's -- part of a chain known as the Ogasawara Islands, sometimes called the Bonin Islands.

"This is a great example of how volcanic island like this in the Bonin Islands grow over hundreds to thousands of eruptions," volcanologist and blogger Erik Klemetti wrote in a post for Wired earlier this year.

When it first emerged, scientists didn't think Niijima would last much more than a few years. But with its continued growth -- it's now six-tenths of a mile across and nearly 200 feet tall -- it may stick around for longer.

"A lot of it depends on how fast it erodes," Ken Rubin, a professor at the University of Hawaii at Manoa and an expert in submarine volcanism, told CNN. "Until it shuts off, it's too soon to tell."

Ecuador's 'throat of fire' belches giant ash column
Quito (AFP) April 05, 2014
A volcano in central Ecuador spewed up a column of hot ash and smoke 10 kilometers (six miles) high on Friday, increasing fears of an eruption. Activity has been building at the Tungurahua volcano 130 kilometers south of the capital Quito since early February, and on Friday experts reported a loud explosion "that lasted for five minutes" and an expulsion of ash. "For now ashfall is mild, ... read more
