Thu, 4 Jun 2015, 11:05 | BY: T
PVMBG reported that during 22 April-25 May diffuse white plumes rose 25 m above Anak Krakatau, although foggy weather often prevented observations.
Seismicity was high during May, and continued to be dominated by shallow and deep volcanic earthquakes, and signals indicating emissions. The Alert Level remained at 2 (on a scale of 1-4). Residents and visitors were warned not to approach the volcano within 1 km of the crater.
