**La Jolla, CA** – Scientists at UC San Diego’s Scripps Institution of Oceanography are making significant strides in their quest to predict dangerous coastal bluff collapses before they happen. Using sophisticated technology, they have successfully anticipated several landslides in North San Diego County, sometimes more than a day in advance.
“There are things that are detectable before landslides occur,” explained Mark Zumberge, a research geophysicist at Scripps. “We’ve had three cases where it was pretty clear something was going to happen.”
This research, fueled by the tragic 2019 Grandview Beach collapse that claimed the lives of three family members, holds the potential to save lives.
The team is currently focusing on installing advanced sensors along the bluffs in Del Mar and Encinitas to gather more detailed data. While further analysis is needed to ensure reliability, researchers are optimistic that an early warning system is feasible.
“What we’re seeing so far is quite promising, that we will be able to use these signals in the future to develop a system,” said Adam Young, a Scripps researcher.
Patrick Davis, who lost his wife, daughter, and sister-in-law in the Grandview Beach tragedy, believes this research could be a vital step in making coastal bluffs safer.
“I think this could be just a really valuable step in making the bluffs a lot safer,” Davis said. “That could be a real solution.”
The scientists are utilizing a variety of technologies, including tiltmeters, which measure subtle shifts in the land, and LiDAR, which provides detailed topographical data. They are also developing custom-built sensors that use optical fiber and lasers for even more precise measurements.
The goal is to deliver a report to lawmakers in early 2026 with recommendations for developing an early warning system. While the researchers are not tasked with issuing warnings themselves, they hope their findings will pave the way for a comprehensive system overseen by another organization.
Assembly member Tasha Boerner, who authored the legislation that sparked this research, envisions a pilot program by 2030 and widespread implementation across the West Coast by 2035.
“My hope would be by 2030, the pilot (warning system) would be going across California in these selected locations that are most acutely experiencing bluff collapses,” Boerner stated.
This research is not only driven by a desire to prevent future tragedies, but also by a commitment to honor the memory of those lost in the Grandview Beach collapse. The Davis family’s lawsuit against the state of California, city of Encinitas, and a local homeowners association is nearing a $30 million settlement. Beyond financial compensation, the family is advocating for policy changes to improve safety along California’s coastlines.
