The Prague Post - Rescuers say no more signs of life in rubble of collapsed Indonesian school

Part of the multi-storey boarding school on the main island of Java collapsed suddenly on Monday as students gathered for afternoon prayers.

Five people have since been confirmed dead and 59 people were still feared buried under the rubble after days of rescue operations.

"We used high-tech equipment like thermal drones, and, scientifically, there were no more signs of life," said Suharyanto, the head of Indonesia's disaster mitigation agency.

Distraught families waited anxiously near the site for news of their loved ones. Many burst into tears upon hearing there were no signs of life, and one woman fainted, AFP journalists saw.

Residents near the school opened their homes to families as they waited, while charities set up posts offering food and drink.

"I've been here since day one. I am hoping for the best news, that my brother survives. I am still hopeful," said Maulana Bayu Rizky Pratama, whose 17-year-old brother is missing.

"It's been four days, I hope my brother will be found soon. I feel sad thinking of him being down there for four days," the 28-year-old said.

Dewi Sulistiana, whose 14-year-old son is missing, said authorities had taken a DNA sample from her. "I want him found so we can bring him home and bury him," she said through tears.

Rescuers pulled five survivors from the rubble on Wednesday as frantic parents demanded that they speed up efforts to find dozens of children they believed were still trapped.

Abdul Hanan, whose 14-year-old son is missing, said children trapped under the rubble had been crying for help.

"The rescue operation must be accelerated," he said.

Suharyanto, who, like many Indonesians, uses only one name, hoped that not all of the missing were trapped under the rubble, citing a case where a woman mourned her son only to discover later that he was alive.

Investigations into the cause of the collapse in the town of Sidoarjo are continuing but initial signs pointed to substandard construction, experts said.

- Complex operation -

The rescue operation is complex because vibrations happening in one place can affect other areas, said Mohammad Syafii, head of the National Search and Rescue Agency.

"So now, to reach the spot where the victims are, we have to dig an underground tunnel," he told reporters.

Any tunnel will only provide an access route around 60 centimetres (25 inches) wide because of the structure's concrete columns.

The families of the missing agreed on Thursday for heavy equipment to be used, Pratikno, coordinating minister for human development and cultural affairs said, adding that rescuers would exercise "extreme caution".

One crane was already working to clear the rubble and four more were expected to be deployed to speed up recovery efforts as the 72-hour "golden period" for the best chance of survival came to an end.

However, the operation could last longer than seven days if people are still missing, a search and rescue agency official told AFP.

Families have been able to follow the search and clearing work live on a television screen set up near the site.

The school collapse was so violent it sent tremors across the neighbourhood, said resident Ani.

"I felt a vibration and then I heard a noise. I immediately ran to save myself. I didn't realise at first it was a building collapse," the grocery stall owner told AFP.

The rescue operation was complicated by an earthquake that struck overnight on Tuesday, briefly halting the search.

The building collapsed after its foundation pillars failed to support the weight of new construction on the fourth floor of the school, the national disaster management agency spokesman said.

At least three people were killed and dozens injured this month when a building collapsed in West Java province during a prayer recital.
