Three days after a small explosive eruption on 17 July 1918 a lava dome formed above the surface of the lake, filling the crater. By the time the eruption ended on 30 July the dome had grown to a height of 85 m and to a width of 440-560 m. The lava dome was later destroyed by explosive eruptions in 1982.
