Indonesia’s Anak Krakatau eruptions give rise to two new islands

Saturday 03 - 16:30

Two new islands have emerged near Indonesia’s Anak Krakatau volcano following a series of eruptions last month, according to the country’s Center for Volcanology and Geological Hazard Mitigation (PVMBG).

The newly formed landmasses were identified through satellite imagery and are located less than one kilometer from Anak Krakatau. Their appearance highlights the continuing ability of volcanic activity to reshape the landscape around one of Indonesia’s most closely monitored volcanoes.

Satellite images reveal the changes

PVMBG officials said the formations were detected through observations of the area surrounding the volcano. The emergence of the islands followed several eruptive episodes that affected the region in recent weeks.

The new formations are situated close to the volcanic cone, making continued monitoring particularly important as Anak Krakatau remains an active geological site. Satellite observations provide authorities with a way to track changes in terrain and volcanic activity, particularly in areas where direct access can be difficult or dangerous.

Eruptions disrupt air transport

The recent volcanic activity also had consequences beyond the immediate vicinity of the volcano. The eruptions contributed to disruptions that affected Indonesia’s main airport, highlighting the wider impact that volcanic activity can have on transport infrastructure and daily life.

Indonesia sits along the Pacific Ring of Fire and is home to a large number of active volcanoes. Anak Krakatau, which emerged from the remains of the historic Krakatau volcanic complex, has undergone repeated episodes of activity since its formation.

A landscape shaped by volcanic forces

The appearance of the two islands illustrates how rapidly volcanic processes can alter Indonesia’s coastal environment. New deposits of lava, ash and other volcanic material can accumulate around an erupting volcano, potentially creating new sections of land above sea level.

For Indonesian authorities, the priority remains monitoring the volcano and surrounding waters as activity evolves. Further observations will help determine how stable the newly emerged formations are and whether additional changes occur around Anak Krakatau.
