An eruption that began on 9 July 1992 produced a small tuff cone on the floor of the Pinatubo caldera. On 14 July a new lava dome was sighted, which by the end of the eruption on 30 October had grown to a height of more than 100 m and a diameter of 300 x 400 m. This view from the S shows the dome on 8 March 1993. Subsequent rise of the lake level covered much of the dome by 1994, leaving two small islands in the caldera lake.
