Indonesian rescuers struggle against heavy rain to reach tsunami-hit villages

Clouds of ash spewed from the nearby Anak Krakatau, or child of Krakatau, almost obscuring the volcanic island where a crater collapse at high tide on Saturday sent waves up to 5 meters (16 feet) high smashing into the coast on the Sunda Strait, between Java and Sumatra islands. Indonesia's meteorology agency (BMKG) said the rough weather could make the volcano's crater more fragile. "We have developed a monitoring system focused specifically on the volcanic tremors at Anak Krakatau so that we can issue early warnings," said BMKG head Dwikorita Karnawati, adding that a two-kilometer exclusion zone had been imposed.
