Widespread flooding in Đà Nẵng in the wake of Typhoon Ketsana.
Đà Nẵng is susceptible to damage from typhoons that cross into the South China Sea. In 2006, the landfall of Typhoon Xangsane near the city of Huế caused 26 deaths in Đà Nẵng, damaging and destroying homes, downing trees and power lines and flooding major streets.
Authorities in Đà Nẵng estimated the damage caused by Xangsane at around US$ 200 million, with more than 5,000 houses washed away, 166,000 homes damaged and 19 boats sunk. Three years later, Typhoon Ketsana made its landfall about 37 miles (60 km) south of Đà Nẵng, again causing widespread flooding. Ketsana left eight people dead and 96 injured in Đà Nẵng, and caused an estimated billion in damage.
Shortly after the 2011 Tōhoku earthquake, which triggered a powerful tsunami, the People’s Committee of Đà Nẵng approved the installation of 10 early tsunami warning stations throughout the city, the first of their kind in Vietnam. Officials expected the stations would provide at least thirty minutes of warning in case of a tsunami. According to Le Huy Minh, Director of the Earthquake and Tsunami Warning Centre at the Vietnam Institute of Geophysics, a powerful earthquake (≥8 MW) in the waters north of the Philippines could pose a significant danger to the Vietnamese coastline, particularly the area around Đà Nẵng.
