Environment Minister Jumhur Hidayat Deploys Rapid Response Team Over Krakatau Eruption Effects

Environment Minister/Head of the Environmental Control Agency (KLH/BPLH) Mohammad Jumhur Hidayat said the government will carry out coastal ecosystem recovery and address biological impacts caused by volcanic activity at Mount Anak Krakatau once conditions are declared stable.

At present, he said, the Ministry of Environment/BPLH is focusing on intensive monitoring of conditions on the ground following the continuous eruption of Mount Anak Krakatau.

“The Ministry of Environment’s Rapid Response Team has been deployed to measure ambient air quality (outdoor air in open environments), as well as to monitor seawater quality along the coasts of Banten and Lampung,” Jumhur said in an official video statement quoted on Monday (7 September 2026).

“We urge communities in affected areas to remain calm and to always wear masks when carrying out activities outdoors. Also, please comply with advisories from the National Disaster Management Agency (BNPB) and the Centre for Volcanology and Geological Hazard Mitigation (PVMBG),” he stressed.

Jumhur also reminded regional governments in areas affected by the eruption of Mount Anak Krakatau to step in to secure household clean water sources from contamination by volcanic ash.

“In responding to the eruption of Mount Anak Krakatau over the past two days, I convey this message and appeal: the Ministry of Environment continues to intensively monitor the ecological impacts of the volcanic activity of Mount Anak Krakatau in the Sunda Strait. At present, the government’s top priority is mitigating environmental impacts and protecting the public,” Jumhur stressed.
