Indonesia: No-fly zone introduced around erupting Anak Krakatau volcano Dec. 27

Event

As of Thursday, December 27, local authorities ordered airliners to steer clear of the Anak Krakatau volcano and raised the danger level of the erupting volcano to the second-highest level (on a four-level scale, with level 4 the highest). The Anak Krakatau has been more active in the past few days, rejecting columns of ash of up to 3 000 m. Meanwhile, the no-go zone around Anak Krakatau has been widened (from 2 km to 5 km in radius). Commercial flights (around Anak Krakatau) have been diverted. So far, flights to and from Soekarno-Hatta airport (CGK), located 150 km (93 mi) east of the Anak krakatau, have not been impacted by the consequences of the eruption.

Context

A 1 m (3 ft) surge of water hit the Sunda Strait on Saturday, December 22. The wave was caused by an undersea landslide following an eruption at the Anak Krakatau volcano. Authorities did not issue a tsunami warning because no earthquake was recorded prior to the wave hitting the coast. 430 people were killed, 160 remain missing, and 1,500 were injured after an eruption at the volcano triggered killer waves which slammed into coastal areas in western Java and south Sumatra.

Advice

Individuals in the affected areas are advised to adhere to all instructions issued by local authorities and anticipate infrastructure damage and disruptions, including for transportation and telecommunication.
