BMKG says Anak Krakatau ash is currently not heading toward Jakarta

Volcanic ash from the latest eruption of Anak Krakatau is not currently heading toward Jakarta, Indonesia’s Meteorology, Climatology and Geophysical Agency, BMKG, said.

BMKG Deputy for Science and Technology Guswanto said the agency monitors the impact and atmospheric movement of volcanic ash, while the Center for Volcanology and Geological Hazard Mitigation is responsible for monitoring the eruption itself.

The ash that came out today is no longer being observed heading toward Jakarta.

Several days earlier, BMKG detected two ash movement clusters. Ash at an altitude of 50,000 feet moved west, while ash between 12,000 and 15,000 feet moved east. The eastward movement disrupted operations at several airports.

At an altitude of 50,000 feet, its movement was toward the west.

Guswanto said Anak Krakatau erupted again, but current monitoring did not show the ash moving toward Jakarta. He said winds were expected to move west under the influence of easterly winds blowing from Australia toward Asia. He also cautioned that the atmosphere is complex and has different layers.

Jakarta officials have carried out water-mist operations on several roads to reduce volcanic dust and particles in the air and on road surfaces. The provincial government has also monitored air quality and advised people to wear masks while outdoors.

At an altitude of 12,000 to 15,000 feet, it moved eastward, and this eastward movement caused disruptions at several airports.
