While falling masonry and collapsed buildings are the main cause of injury and death in an earthquake, it is only recently that Indonesia began to tighten its construction regulations. Over the p ast 30 years, Indonesia has reported an average of 289 significant natural disasters each year with an average annual death toll of about 8,000 people, according to the Global Facility for Disaster Reduction and Recovery.
The US, Japan and maybe a few other countries are state of the art on this, but it has not spread throughout the world.” “We should be able to design a control tower to withstand that, but this is complex science, complex research, and complex engineering. “ was a complex disaster,” said Elizabeth Hausler, founder and CEO of Build Change, which works in developing countries, including Indonesia, to help local communities build homes that can better withstand natural disasters. Palu also saw widespread soil liquefaction with entire communities disappearing into the resulting mud. The archipelago is vulnerable to a range of other natural disasters including landslides, tsunamis and volcanic eruptions, which make it even more complicated to build structures that can survive the impact. It’s not only earthquakes that put Indonesians at risk.
There’s got to be an effort to manage risk.”
“This is the right moment for us structural mitigation and non-structural mitigation. “I see that these earthquakes are our wake-up call,” Raditya Jati, director of disaster risk reduction at Indonesia’s National Agency for Disaster Management (BNPB), told Al Jazeera. WATCH: Over 70,000 homeless after Indonesia disaster (1:42) Just two months before the Sulawesi disaster, two earthquakes rocked the island of Lombok, killing 500. Indonesia is one of the world’s most disaster-prone countries, experiencing seismic activity on an almost daily basis and an earthquake of magnitude 5 about once a week on average. The Mercure hotel overlooking the city’s distinctively shaped bay, the Ramayana shopping centre, hospitals, schools and the airport’s control tower were all badly damaged in the disaster, which left more than 2,100 people dead and hundreds missing. The Roa Roa, which was completed in 2014, wasn’t the only major building that failed in the quake and the tsunami that followed. Staff and guests rushed to escape as the magnitude 7.5 quake cracked the hotel’s concrete columns, reducing the building to a pile of twisted steel and rubble. As evening fell, some guests headed out for dinner. Just under half the hotel’s 50 rooms were booked on the last Friday of September, many of them by athletes competing in a gliding championship that was taking place nearby. The seven-storey Roa Roa Hotel, with its clean lines and bright blue decor, was one of the few high-rises in the small Indonesian city of Palu, on Sulawesi Island, offering a dash of style to visitors on a budget.
