PVMBG reported that cloudy weather often prevented visual confirmation of the ongoing eruption at Anak Krakatau during 9-16 August.
Incandescence at or near the vent was seen in nighttime photos on most days.
The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay at least 5 km away from the crater.
