{{B}}Japanese Drilling into Core of Earth{{/B}} In what
resembles a journey to the center of the Earth, Japanese scientists have
launched the world’s first attempt to bore a hole into the red-hot core of a
volcano and unlock the secrets of deadly eruption. A
50-meter-high oil-rig-like derrick perched on the scrubby slopes of Japan’s
Mount Unzen will begin drilling through the volcano’s crust next week in a bid
to sample the magma bubbling below. The aim is to study how the
liquefied rock causes menacing gas buildup, said team leader Setsuya Nakata, of
the University of Tokyo’s Earthquake Research Institute.
"Gassing is important because it controls the explosivity of eruptions,"
Nakata said. "The result A. erupted in 1707. B. erupted in 1991. C. erupted in 1995. D. several times in the last century.
