Hawaii at Risk: Study Reveals Accelerated Sinking of the Islands

Hawaii, considered one of the world’s top surfing destinations, may be facing a significant natural threat. A recent study from the University of Hawaii, published by Surfer magazine, revealed that parts of the islands are sinking into the ocean at a much faster rate than previously thought.

Is Hawaii Really Sinking?

The study, led by Kyle Murray from the Climate Resilience Collaborative (CRC), showed that while the average subsidence rate in Oahu is about 0.6 mm per year — comparable to the thickness of a sheet of paper — certain areas of the island are sinking up to 40 times faster, exceeding 40 mm annually. This phenomenon suggests that some regions could experience frequent flooding much sooner than expected.

It’s important to note that Oahu is home to some of the most iconic surfing spots, especially the North Shore, where Pipeline, one of the world’s most famous and challenging waves, is located.

What Are the Practical Consequences?

According to Phil Thompson, director of the UH Sea Level Center, areas such as the industrial district of Mapunapuna could experience up to 50% more flooding by 2050. This scenario also significantly reduces the time available to implement adaptation measures, shortening the timeline by about 50 years.

The study emphasizes the importance of this data for both the local government and residents to act preventively and mitigate the impacts caused by accelerated sinking.

“Our work provides essential information for urban planning and infrastructure resilience in Hawaii,” said Chip Fletcher, co-author of the study. “This data is crucial to protect the local community and ensure a safer future for everyone.”
