Steam emission from the blocky summit of a lava dome formed during a submarine eruption at the Beyonesu Rocks vent of the Myojinsho caldera in 1952. This 22 September photo was taken six days after the dome began to breach the sea surface. Later that day the eruption became highly explosive and the dome was destroyed. Three cycles of dome growth and destruction occurred until October 1953.
