The eruption of Anak Krakatau is suspected to be the cause of the booming sound and vibrations felt by people in Greater Bandung, Banten, and Lampung based on monitoring by the Geological Agency.
The mysterious booming sounds heard in Greater Bandung and several areas of West Java, Banten, and Lampung from Friday (September 4, 2026) evening to Saturday (September 5, 2026) early morning are suspected to be related to the eruption of Mount Anak Krakatau (GAK) in the Sunda Strait. So, is the boom really from the eruption of Mount Anak Krakatau?
