@jxself The volcano is on a peninsula, so there's no imminent danger that the lava could reach the nearby city of Kagoshima:

Right now, Mauna Loa in Hawaii is also erupting with spectacular lava fountains.
Check the live steam:

@srevinsaju @jxself It's possible if you can find workers willing to dig a trench while a river of lava is approaching from above, the ground is exhaling asphyxiating gasses, and the crater could explode any time, ejecting molten rocks and ashes that will rain over the entire island.
