An international research team successfully completed an ambitious drilling project to investigate the fault that ruptured during the Tohoku earthquake that devastated Japan in 2011 .

At an extreme water depth of 7 kilometers , the team used the Japanese drilling vessel Chikyu to drill a series of deep boreholes.

The team's geologic and hydrologic testing will increase understanding of subduction zones and lead to better preparation for large earthquakes.

Cornell University has drilled down more than 900 meters across the fault.

The observatory contains ultra-sensitive sensors to measure the fluid flowing through the fractures and frictional heat.

Fulton expects the data they've collected will generate a number of research papers in the coming years .

The project concluded in December with the construction of a new, even deeper borehole observatory.
