The strait between Java and Sumatra, linking the Java Sea to the Indian Ocean
Anak Krakatau has erupted since late Friday and has produced lava fountains and ash clouds that reached up to 50,000ft. Authorities have suspended operations at Soekarno‑Hatta and at least seven other airports, delaying more than 200 flights and affecting over 22,000 passengers. Officials have kept a 3km exclusion zone and urged people to protect themselves from ash.
A speedboat carrying five photojournalists, two crew members and a route guide has lost contact after leaving Carita, Banten, bound for Anak Krakatau in the Sunda Strait. The last message placed them near the island's waters; rescuers are still unable to locate them as Anak Krakatau remains active and flights in the region are disrupted.
