Indonesia hikes danger level for deadly tsunami volcano
The no-go zone around Anak Krakatoa has been widened from 2km to 5km amid warnings of more eruptions
Indonesia on Thursday raised the danger alert level for an erupting volcano that sparked a killer tsunami at the weekend, after earlier warning that fresh activity at the crater threatened to trigger another deadly wave.
Authorities also widened a no-go zone around rumbling Anak Krakatoa to 5km, up from a previous 2km, and warned shell-shocked residents to stay away from the coast, after more than 400 were killed by Saturday night’s wave.
Plumes of ash spat 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 spokesperson Sutopo Purwo Nugroho. He said people nar the volacano could be hit 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.
‘Just pray for us’
The new flows posed no immediate danger to nearby towns as the volcano sits in the middle of the Sunda Strait between Java and Sumatra islands.
But the status change sparked new fears among many residents already scared and refusing to return to their communities.
“This worries me,” said Ugi Sugiarti, a cook at the Augusta Hotel in hard-hit Carita. “I’ve already left.”
Sukma, a security guard at the shattered Mutiara Carita Cottages, added: “Just please pray for us and that everything will be okay.”
A section of the crater, which emerged at the site of the Krakatoa volcano, whose massive 1883 eruption killed at least 36,000 people, collapsed after an eruption and slid into the ocean, triggering Saturday night’s killer wave.
Before-and-after satellite images taken by Japan’s space agency showed that a 2km² chunk of the volcanic island had collapsed into the water.
At least 430 people were killed in the disaster, with 1,495 people injured and another 159 missing.
Nearly 22,000 people have been evacuated and are living in shelters.
On Wednesday evening, the disaster agency said wind was blowing “ash and sand” from the volcano to the nearby towns of Cilegon and Serang on Java, and advised residents to wear masks and glasses if they had to venture outdoors.
Early warning system
Torrential rains have sparked flooding in some areas, hampering the relief effort and heaping more misery on the stricken region, as thousands cram emergency shelters.
Medical workers have warned that clean water and medicine supplies are running low, stoking fears of a public health crisis.
Indonesia is one of the most disaster-hit nations on Earth due to its position straddling the so-called Pacific Ring of Fire, where tectonic plates collide.
The tsunami was Indonesia’s third major natural disaster in six months, following a series of powerful earthquakes on the island of Lombok in July and August and a quake-tsunami in September that killed about 2,200 people in Palu on Sulawesi island, with thousands more missing and presumed dead.
The disaster agency has said it installed new sensors to better monitor tremors at the volatile volcano.
The agency initially said there was no tsunami threat at all, even as the killer wave crashed ashore.
It was later forced to issue a correction and an apology as it pointed to a lack of early warning systems for the high death toll.
One of the hardest-hit areas, Tanjung Lesung, is on a list of 10 destinations that Jakarta wants to turn into another Bali, the holiday island hot spot that draws millions of tourists annually.
“We need to have [tsunami] early warning systems, especially in tourist destinations,” Indonesia’s tourism minister Arief Yahya said on Thursday.
“We’re going to make that happen.” — AFP
