Anak Krakatau eruption closes Indonesian airports
Volcanic ash shut airports around Jakarta and disrupted travel as Anak Krakatau’s activity continued.

What happened
Anak Krakatau began sustained activity late Friday, sending ash across Jakarta and nearby areas. Eight Indonesian airports were closed at the peak, including airports serving the capital. The continuous phase ended Sunday, but intermittent activity continued Monday as authorities kept seven airports closed and moved some schools to remote learning.
