A 150-meter long crack has suddenly widened on the ground of a Shizuoka Prefecture tea farm, while officials evacuated six local households over fears of a landslide.
The crack was found on the slope of a tea plantation in Hamamatsu City, a hilly area where landslides can easily occur. Although it was originally discovered last month, it appeared to be unstable, and the houses nearby were evacuated on Sunday. On Monday, observers from the prefecture measured the crack at 150 meters long and 15 centimeters wide. Over the course of an hour, they saw it widen an astonishing 4 millimeters.
Today, a geological survey will be conducted in the area to assess the danger.
