CARITA: Indonesia on Thursday raised the danger alert level for an erupting volcano that sparked a killer tsunami at the weekend, after previously warning that fresh activity at the crater threatened to trigger another deadly wave, reports AFP.
Authorities also widened a no-go zone around rumbling Anak Krakatoa to five kilometres (three miles) — up from a previous two kilometres—and warned shell-shocked residents to stay away from the coast, after more than 400 were killed by Saturday night’s killer wave.Plumes of ash burst into the sky as pyroclastic flows—hot gas and other volcanic material—flowed down the crater, threatening anyone too close to the volcano and raising the risk of rough seas for boats in the vicinity.
“There is a danger of more eruptions,” said national disaster agency spokesman Sutopo Purwo Nugroho.
“People (near the volcano) could be hit by hot rocks, pyroclastic flows and thick ash.”
Authorities raised the crater’s status to high alert, the second-highest warning on the country’s four-point danger scale, while aviation officials ordered flights to be redirected away from the area.
“We’ve raised the status of (the volcano) since this morning because there’s been a change in the eruption pattern,” Kus Hendratno, a senior official at the Krakatoa observatory, told AFP Thursday.
The new flows posed no immediate danger to area towns as the volcano sits in the middle of the Sunda Strait between Java and Sumatra islands.
