Showa crater is located on the eastern flank of ''Minami-dake'' (Southern Peak) of Sakurajima volcano. Showa crater appeared in 1939 after one month of eruptions that year, at an elevation of 800 feet. It continued to have intermittent eruptions for the next, almost a decade. There was a large lava flow out of Showa crater in 1946, which destroyed the village of Kurokami. In July 1948 Showa stopped erupting and remained quiet for 58 years. The dormancy ended in 2006, when eruptions out the crater resumed.
