Indonesia raises Krakatau to alert level 3 as small eruptions pick up
Indonesia's volcano agency raised Krakatau's alert to level 3 of 4 on 9 October after nine eruptive events in a single day.
What the source says
- Indonesia's volcano agency PVMBG reported an increase in low-level eruptive activity at Krakatau from early October, according to the Smithsonian Global Volcanism Program weekly report for 8-14 October.
- Five eruptive events were recorded from 6 to 8 October, followed by nine on 9 October.
- Minor ash plumes rose as high as 50 m above the crater when the weather allowed a view, and satellite data showed sulfur dioxide emissions of up to 238 tons per day.
- PVMBG raised the Alert Level to 3 (on a scale of 1 to 4) at 2100 on 9 October and advised the public to stay 5 km away from the summit.
- Krakatau sits in the Sunda Strait between Java and Sumatra; its 1883 eruption caused more than 36,000 deaths, mostly from tsunamis, and Anak Krakatau has erupted frequently since 1927.

Nana Flint · opinion
The plumes are small and the gas is low, I'll give the agency that, and a 5 km keep-out is sensible caution rather than panic. But this is the mountain whose last big go sent tsunamis down the strait, and Anak Krakatau has form. So who's watching the water as well as the crater, and who tells the fishing villages first?
