"First Contact With Inner Earth": Drillers Strike Magma

A collapsed vent allows hot lava to peek through solidified rock at Hawaii's Kilauea volcano in an undated photo. For the first time on record, workers drilling at a geothermal plant near Kilauea accidentally hit a pocket of magma in its natural environment deep inside Earth. Announcing the find at a December 2008 meeting, one volcano expert likened the discovery to a paleontologist finding a dinosaur romping on a remote island.

From National Geographic:

A drilling crew recently cracked through rock layers deep beneath Hawaii and accidentally became the first humans known to have drilled into magma—the melted form of rock that sometimes erupts to the surface as lava—in its natural environment, scientists announced this week.

"This is an unprecedented discovery," said Bruce Marsh, a volcanologist from Johns Hopkins University in Maryland, who will be studying the find.

Normally, he said, volcanologists have to do "postmortem studies" of long-solidified magmas or study active lava during volcanic eruptions.

But this time they'd found magma in its natural environment—something Marsh described as nearly as exciting as a paleontologist finding a dinosaur frolicking on a remote island.

"This is my Jurassic Park," he said at a meeting of the American Geophysical Union meeting in San Francisco.
