C. Uhlig and F. Muller climbed the volcano on 4 August 1910 and observed that "the northern crater had only a horse-shoe-shaped southern rim immediately below the summit, and lacked a crater rim to the north, west and east. The crater was more like a platform on which there was a central cone from which gas was being emitted".
Lava flows and pinnacles formed on this platform between 1904 - 1910 and again between 1913 - 1915.
