A recent visit at the summit of the volcano by our expedition leader Andi and Markus confirmed that "Semeru's lava dome is growing bigger and wider, and now has a diameter of 100-200 m.
Strombolian explosions occur from time to time and eject bombs up to 100 m above the vent. Gas venting from two vents is loud and continuous.
According to our observations, part of the dome has collapsed recently to the south flank. A moderately viscous lava forms a long tongue descending into the southern ravine"
