Mauna Loa, the biggest volcano on Earth, and one of the most active, covers half the Island of Hawaii. Just 35 miles to the northeast, Mauna Kea, known to native Hawaiians as Mauna a Wakea, rises 14,000 feet above sea level. To them it represents a spiritual connection between our planet and the heavens above.

Hawaiian volcanos

These volcanoes, which have beguiled millions of tourists visiting the Hawaiian islands, have also plagued scientists with a long-running mystery: If they are so close together, how did they develop in two parallel tracks along the Hawaiian-Emperor chain formed over the same hot spot in the Pacific Ocean — and why are their chemical compositions so different?

We knew this was related to something deeper, but we couldn’t see what,

said Tim Jones, an earth science Ph.D. student at Australian National University and the lead author of a paper published in Nature on Wednesday that may hold the answer.

Simulation model

Mr. Jones and his colleagues developed a model that simulates what’s happening in our planet’s mantle, beneath the crust that we live on, offering a window to the center of the Earth — or close to it. Their study may one day allow a reconstruction of the history of the movement of Earth’s plates — and the processes linked to these movements over billions of years, like mass extinction events, diamond and oil deposits, and changes in climate.

If you were to drill nearly 4,000 miles into the Earth, you’d reach its core, a ball of solid iron surrounded by liquid that scientists estimate is hotter than the sun. Before making it there, you’d hit the mantle — an 1,800-mile-thick layer of solid rock that can flow like a liquid, just substantially slower. This mantle is the reason plates move across the surface.

Deep into Earth's crust

It’s why we have continents, earthquakes and volcanoes. The closest anyone ever got to the mantle was a seven-mile-deep hole drilled into the crust on a peninsula in western Russia. But now we can better understand what’s happening below by looking at Mauna Kea and Mauna Loa, said Mr. Jones. The prevailing hypothesis has been that volcanoes like these two in Hawaii are chemical fingerprints of the Earth’s composition at the deep mantle, just at the border of its core.

What seismic activity reveals?

But that didn’t explain the separate tracks along which the volcanoes formed.

Scientists have seismic evidence that the deep part of the mantle is a graveyard where long ago slabs of earth were subducted, creating separate regions with different chemical compositions that eventually made their way to the surface in a hot mantle plume as the core heated the rock into magma.

Bottom line

By examining data from the two volcanoes, Mr. Jones and his team suggested an alternative: The chemical signature, along with this double-track volcanism as it’s called, occurred three million years ago when the plates above the hot spot shifted direction, moving north.

This shimmy rearranged zones of magma that are heated under different pressures in the shallower part of the mantle — when they cool, the volcanic rock that results reflects this difference. Previously stacked on top of one another, the movement of the plates exposed now geographically separates magma zones that fed the volcanoes individually.

  4. I precisely had to say thanks again. I do not know the things that I could possibly have taken care of without the type of recommendations documented by you regarding that area. It was a very frustrating setting in my circumstances, however , looking at a new professional approach you treated the issue forced me to cry over delight.

  5. Hmm it looks like your blog ate my first comment (it was super long) so I guess I’ll just sum it up what I had written and say, I’m thoroughly enjoying your blog. I too am an aspiring blog blogger but I’m still new to everything. Do you have any helpful hints for beginner blog writers? I’d really appreciate it.

  6. Generally I do not read article on blogs, but I wish to say that this write-up very pressured me to check out and do it! Your writing style has been surprised me. Thanks, very great article.
