Hotels along Bali’s beaches are in danger of collapse due to the disappearance and erosion of sub-surface soil. This condition is caused by the acute depletion of water reservoirs that creates large subterranean caverns and the danger of subsidence.
As reported by Beritabali.com, the chairman of the Center for Sustainable Development at Bali’s Udayana University, Dr. Dharma Putra, says the tendency of subsidence along Bali’s beaches is predicated on the intrusion of seawater into the water table. Saltwater intrusion is now estimated to have penetrated to a distance of 20-25 meters inland in some areas along Bali’s coastline. Putra warns that hotels in these areas could someday collapse due to growing caverns hidden underground.
Dr. Dharma Putra continued, “actually, in terms of construction, new hotels have already prepared for this contingency; it is the older hotels that are risk.” He went on to explain that hotels in Nusa Dua or on the Ungasan peninsula are relatively safe, built on limestone and coral. He contends the hotels most in danger of collapse are located in Kuta where the soil composition is mostly sand.
The respected academic flagged Kuta, Tanjung Benoa and Sanur as the areas where saltwater intrusion is most acute in Bali.
