The eruption was on Mount Fuji's east–north-east slope and made three new volcanic openings called No. 1, No. 2, and No. 3 Hōei vents. The danger of the eruption increased over the next several days. After the first earthquake and explosion of cinders and ash, another stronger explosion happened a few days later. This explosion threw out rocks and stones. Mount Fuji has not erupted since; but scientists describe Fuji as an active volcano.
