THE CALIFORNIA COAST GREW AND PROSPERED during a remarkable moment in history when the sea was at its tamest. But the mighty Pacific, unbeknownst to all, was nearing its final years of a calm but unusual cycle that had lulled dreaming settlers into a false sense of endless summer. Elsewhere, Miami has been drowning, Louisiana shrinking, North Carolina’s beaches disappearing like a time lapse with no ending. While other regions grappled with destructive waves and rising seas, the West Coast for decades was spared by a rare confluence of favorable winds and cooler water. This “sea level rise suppression,” as scientists call it, went largely undetected. Blinded from the consequences of a warming planet, Californians kept building right to the water’s edge. But lines in the sand are meant to shift. In the last 100 years, the sea rose less than 9 inches in California. By the end of this century, the surge could be greater than 9 feet.

California Coastal Landslide Early Warning Research

Coastal landslides threaten public resources, coastal infrastructure, and public safety, throughout the state of California. Rising sea levels, coastal populations, and tourism will intensify the risks. Over two dozen people have died from coastal cliff collapses on California beaches. Therefore, understanding the processes and timing of coastal landslides is critical for improved coastal management and hazard mitigation. To address this issue, Assemblymember Tasha Boerner introduced California Assembly Bill 66, and subsequently Assembly Bill 72, which authorized Scripps Institution of Oceanography at UC San Diego to conduct research on coastal cliff landslides and provide recommendations for developing a coastal cliff landslide early warning system.
