The volcano’s activity has been characterized by heightened activity over the past two months.
In the early morning at 03:21 local time, a spectacular vulcanian eruption showered the upper edifice with bright lava bombs associated with ash emissions, releasing to an altitude of 4,325 meters (14,400 feet) in the northern and northeastern direction. The incandescent material landed on the outer caldera flanks, thrown approximately 750 meters from the cinder cone.
The PVMBG volcano observatory reported a seismic signal with a maximum amplitude of 28 mm and a duration of 199 seconds.
At Level IV (AWAS), people are advised to avoid the area within a radius of 4 km and 7 km from the crater.
The warning bulletin states that lahars (mud flows) could occur if heavy rainfall remobilizes fresh ash deposits and may pose a threat to inhabited areas.
