Mount Aso in Kyushu, Japan erupted yesterday and sent absolutely massive clouds of ash billowing into the sky.
Watching those clouds rush across the ground towards the cameraman looks like something straight out of a movie. Hopefully the person recording the video got the hell out of there quickly.
Japan has seen numerous volcanic eruptions over the last couple of months. Multiple volcanos have erupted near Iwo Jima, and have actually caused the hulls of sunken ships from 80 years ago to rise above the surface. You can check that out here.
