A recently finished three-year study from Japan has discovered a new fault line running beneath Mount Fuji, which towers over 12,000 feet above sea level.
Analysis done on the fault line by the University of Tokyo shows the potential for a magnitude 7.0 quake, which could result in a collapse of part of the national landmark and tourist attraction.
Director for earthquake investigation at the science ministry, Yasuhiro Yoshida said "It's possible that the mountain could collapse with mudslides flowing to Gotemba," a city near the base of the mountain.
Further analysis will be done to determine the full effects of an earthquake on the mountain, such as a possible eruption or devastating landslides.
Mount Fuji last erupted in 1707, less than two months following a 8.6 magnitude earthquake centered in the region.
The nation of Japan remains on heightened alert for natural disasters following the deadly earthquake and tsunami in early 2011.
