Indonesia instructs flights to steer clear of erupting volcano

LABUAN, Indonesia - Indonesia on Thursday raised the alert level for the erupting Anak Krakatau volcano to the second-highest, and ordered all flights to steer clear, days after it triggered a tsunami that killed at least 430 people.

A crater collapse on the volcanic island at high tide on Saturday sent waves up to 5 meters high smashing into the coast on the Sunda Strait, between the islands of Java and Sumatra.

Authorities have warned that the crater of Anak Krakatau, or child of Krakatau, remains fragile, raising fears of another collapse and tsunami, and have urged residents to stay away from the coast.
