BMKG Stasiun Meteorologi Ahmad Yani Semarang melaporkan hasil paper test pada Senin (7/9/2026) menunjukkan belum ada sebaran abu vulkanik Gunung Anak Krakatau di wilayah Semarang. Kondisi tersebut terjadi karena angin musim timur membawa sebaran debu vulkanik ke arah barat, seperti Lampung, Bengkulu, dan Palembang. BMKG juga menegaskan tidak memantau sulfur dioksida (SO2) dan mengimbau masyarakat memverifikasi sumber informasi sebelum menyebarkannya.
