The volcano continues to be active, and produce natrocarbonatite lava that slowly fills up the crater. A small cone of natrocarbonatite lava is forming on the western side of Lengai's crater, which formed in 2008 during a series of violent explosions that destroyed the former bizarre crater terrace filling the north crater, famous for the bizarre "hornitos" of white and gray lava.
Gian Schachenmann, who climbed the volcano recently, did not see major changes since September last year. From the rim, one could hear the slushing of lava inside the crater and big cracks were observed on the NW crater rim near the top, with lots of gasses coming out.
Michael Dalton reported that the local people around the volcano have recently felt an increased number of earthquakes and think that some more activity could be coming soon.

Also there we signs that new cone has had some more minor collapses on the inside. He could not tell 100%, but there looks like a small lava lake. ... Read all
