Due to the heightened activity over the past month, the PVMBG raised the volcano’s alert level from Level II (WASPADA) to Level III (ALERT) on 8 May.
The volcano’s explosions produce above-average sizes, and eruption column heights range between 1500 and 2000 meters, generating copious grey ash emissions. In addition, strong incandescence, mainly visible at night, accompanies explosions, indicating a rise of fresh magma within the volcano’s feeder pipe.

In level III (ALERT), people are advised to avoid the area within a radius of 3 km and 5 km from the crater.

Last night at about 00:24 local time, a spectacular towering ash plume was seen rising from the cinder cone. The eruption generated ash emissions that rose 13,123 ft (4,000 m) above the summit and dissipated towards the north-northwest.
