World Record Reached and Broken by Japanese Deep-Sea Drilling Operation

A Japanese deep-sea drilling probe has set a new world record for depth, reaching 7,740 meters 25,400 feet below the sea surface, the research institute that launched it says.

The Chikyu, operated by the Japan Agency for Marine-Earth Science and Technology, was digging the seabed off Japan’s northern coast to take fault samples and study last year’s devastating earthquake and tsunami.

The agency said Friday that the probe’s drilling pipe hit the fault zone at 6,883.5 meters 22,600 feet undersea before reaching the target of 7,740 meters Wednesday. That’s nearly 8 kilometers – 5 miles deep.
