A recent study from the University of Hawaii Manoa reveals that certain areas in Hawaii are sinking into the ocean at an accelerated rate. This subsidence, combined with rising sea levels, means that flooding will occur sooner than anticipated, particularly affecting low-lying regions such as Waikiki and urban Honolulu. Oahu faces significant risks to its infrastructure, with over $12.9 billion at stake. Identified areas are sinking up to 40 times faster than the average, prompting urgency in future flood preparedness and responses towards climate change impacts in Hawaii.
"Our findings highlight that subsidence is a major, yet often overlooked, factor in assessments of future flood exposure," Kyle Murray, lead author of the study, said in a news release.
"In rapidly subsiding areas, sea level rise impacts will be felt much sooner than previously estimated, which means that we must prepare for flooding on a shorter timeline," he continued.
"Hawaii tourism, coastal development, and ecosystems will face major disruptions. It is projected that over $12.9 billion in infrastructure is at risk from flooding and related damages on Oahu alone," the study continued.
"The rate and localized nature of the sinking surprised the research team," the news release said.
