- One of the world’s busiest airports is sinking fast into the sea as engineers race to save it (irishstar.com)
Kansai International Airport (KIX), a major Asian travel hub, is facing a unique challenge: it’s slowly sinking into the sea. Built on artificial islands in Osaka Bay and opened in 1994, this innovative airport was the world’s first ocean airport. However, the soft clay seabed upon which it rests has proven problematic, causing a steady subsidence since its construction.
The main island has sunk approximately 12.5 feet, while a second island, added later, has sunk a staggering 57 feet. This ongoing issue raises serious concerns about the airport’s long-term stability, particularly as the rate of sinking has increased in recent years.
Adding to these concerns are rising sea levels and the threat of extreme weather. In 2018, Typhoon Jebi caused significant flooding and disrupted airport operations for several days, highlighting the vulnerability of the airport’s infrastructure.
Engineers are working diligently to counteract the sinking. Using advanced technology, they are closely monitoring the subsidence and implementing stabilization measures. These include injecting materials into the ground to strengthen the clay base and prevent further sinking.
Despite these challenges, KIX remains a leading airport in Asia, recognized for its excellent staff and baggage handling. In 2020, it was ranked among the top ten airports worldwide, demonstrating its continued importance in the global aviation landscape.
