Japan’s deepest ocean well drilled off the coast.
Scientists have drilled the world’s deepest oceanic well off the coast of Japan to study earthquakes. It is lower relative to sea level than the borehole in the Mariana Trench.
The well appeared in the Pacific Ocean near the epicenter of the Tohoku earthquake, which occurred in 2011 and led to the disaster at Fukushima-1 nuclear power plant. The hole is more than 26,322 feet below sea level, that’s more than 8,023 meters.
The drilling rig recovered a core sample 37.75 meters long. Researchers expect to use it to learn about ancient earthquakes. It will help develop underwater paleoseismology, a science that collects data on the movements of Earth’s rocks since prehistoric times.
