UH researcher shares new projections of the scope and speed of coastal erosion
April 15, 2025
Sea level rise in Hawaiʻi is progressing at a faster pace than previously thought. A new set of scientific models is showing some surprising projections about the state of our beaches and shorelines.
The research comes from the lab of University of Hawaiʻi at Mānoa professor Chip Fletcher, who has been publishing models of sea level rise and beach loss since 1997.
Richelle Moskvichev, a scientific researcher in Fletcher’s lab, spoke with The Conversation about her team’s new research that was published in Scientific Reports… Read More

Hawaiʻi islands sinking faster in some areas; risk for flooding
March 16, 2025
Some parts of Hawaiʻi are sinking faster than others. That discovery, published recently in a study by researchers at the University of Hawaiʻi at Mānoa, also highlights that as sea level rises, the infrastructure, businesses and communities in these low-lying areas are at risk of flooding sooner than scientists anticipated, particularly in certain urban areas of Oʻahu.
“Our findings highlight that subsidence (gradual caving in or sinking of an area of land) is a major, yet often overlooked, factor in assessments of future flood exposure,” said Kyle Murray, lead author of the study and researcher with the Climate Resilience Collaborative (CRC) at the UH Mānoa School of Ocean and Earth Science and Technology (SOEST). “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… Read more
