The research drilling ship Chikyu has reached the fault that set off the monster
earthquake and tsunami that struck Japan in March 2011, the journal Nature reported in May
2012.
At 6.9 kilometers below sea level and 860 meters beyond that into the Earth’s
crust, the drilling project set a record for depth, the journal reported. The previous
record, 7.05 kilometers total, was set in 1978 by a U.S. vessel.
