Mount Anak Krakatau: What to know about the volcano disrupting Indonesia flights

Mount Anak Krakatau in Indonesia has been erupting since Friday, disrupting flights and daily life as ash spread more than 150 km away, covering Jakarta and nearby areas. On Saturday, several schools canceled activities after reports of eye irritation from the ash, and fishermen stopped fishing trips. By the morning of Sept. 7, eight Indonesian airports, including two in Jakarta, remained closed, affecting at least 170,000 people. Anak Krakatau lies in the Sunda Strait between Sumatra and Java and is a relatively young volcano, formed less than 80 years ago along the Sunda Arc. After major activity in 1883 and repeated eruptions since 1927, authorities placed it at alert level 3 from July 2.
