  • BMKG’s Ahmad Yani Semarang station found no volcanic ash in Semarang during testing on Monday, Sept. 7, 2026.
  • Officials said prevailing easterly winds were carrying ash westward toward Lampung, Bengkulu, Palembang, and surrounding areas.
  • BMKG urged residents to verify information about volcanic ash and sulfur dioxide before sharing it.

No volcanic ash from the Anak Krakatau eruption had been detected in Semarang during testing on Monday, according to the Meteorology, Climatology and Geophysical Agency’s Ahmad Yani station.

BMKG forecaster Harits Syahid Hakim said the morning paper test in Semarang produced a negative result. The agency is monitoring the situation through paper tests and satellite imagery, with satellite observations conducted at least once an hour.

The results in Semarang were negative this morning.

· Harits Syahid HakimA BMKG forecaster reported the result of the volcanic ash paper test in Semarang.

Harits said the tests had remained negative since Anak Krakatau erupted. A morning test at Kertajati Airport in Majalengka, which borders Central Java, also found no ash.

Indonesia is currently experiencing the easterly season, so the winds mainly come from the east toward the west.

· Harits Syahid HakimThe forecaster explained why volcanic ash had not been detected in Semarang.

He attributed the absence of ash in Semarang to the seasonal wind direction. “Indonesia is currently experiencing the easterly season, so the winds mainly come from the east toward the west,” Harits said. He added that the ash was moving toward Lampung, Bengkulu, Palembang, and surrounding areas.

BMKG did not monitor or test sulfur dioxide, Harits said, because the station’s monitoring relied on visualizations and satellite imagery. He urged residents to examine the source of information before sharing claims about the eruption or sulfur dioxide online.

Do not simply grab information from people or social media and then spread it. You must first find out whether the news source and the information source are reliable.
