Anak Krakatau Ash: Where Will the Wind Carry It?
Over the past two days, the spread of volcanic ash has moved away from the summit of Mount Anak Krakatau. What will the days ahead bring?
Anak Krakatau's volcanic ash has spread beyond its peak over the past two days, according to the Center for Volcanology and Geological Hazard Mitigation and VAAC Darwin. The ash reached an altitude of 6,000 feet in the lower atmosphere and was observed moving towards the south-southwest, towards the Indian Ocean. The Regional Meteorology and Geophysics Agency predicts low rainfall for Banten province in September to October 2026, with medium to high rainfall expected to begin in November and peak until early 2027.
This rainfall pattern and wind conditions will inform local policy-making, as the head of Banten's disaster management agency noted that the wind direction on September 9 meant that the eastern provinces of Tangerang, Jakarta, and Bogor were safe from ashfall. The wind speeds and direction at the volcano and surrounding waters have varied throughout the week, with predominantly east-southeast winds in the lower atmosphere and northeast winds in the middle and upper atmospheres.
