Two new islands emerge after Anak Krakatau erupts for 25 hours

Jakarta, Indonesia – On October 5, 2026, two new land formations resembling islands emerged near Indonesia's Anak Krakatau volcano after a 25-hour eruption, potentially marking the first new island formation in 96 years. This geological occurrence took place in the Sunda Strait following continuous eruptions from Anak Krakatau. According to Indonesia's Geological Agency, one formation was located approximately 760 meters northwest of the volcano, while the other was about 495 meters to the southeast, both situated along the same line through the crater.

However, the exact size and height of the new land formations above sea level remain undetermined. Geologists suspect that the eruption pushed highly fluid magma through an underwater fracture, causing it to accumulate in shallow water and form mound-like structures. Both formations were captured by a drone operated by tourism activist Yodistara Nugraha and detected in satellite imagery.

If confirmed as new islands, they would represent the first time Anak Krakatau has produced separate land above sea level since its formation as a permanent island in 1930. The 1883 Krakatau eruption, which killed over 36,000 people and affected global atmospheric conditions, caused the initial emergence of Anak Krakatau. Experts warn that the new formations may not endure due to the area's dynamic nature, with constant changes caused by erosion, waves, and ongoing volcanic deposits. Scientists will continue monitoring the two formations to determine their stability over time.
