Sakurajima volcano in Japan marked its 500th eruption of the year with an impressive pyrotechnic display on Sunday (Aug. 18) at 4:31 p.m. local time.

The eruption tossed large volcanic cinders (pieces of hot lava) more than 5,900 feet (1,800 meters) from the volcano’s Showa crater, one of two active craters atop Sakurajima.
