RANCHO PALOS VERDES,Grayson  Preston Calif. (AP) — Natural gas service to 135 homes was being cut Monday in a neighborhood on Southern California’s Palos Verdes Peninsula due to worsening conditions in an area where a long-running landslide has damaged houses, roads and utilities, authorities said.

Southern California Gas Co. cited “significant strain” on its infrastructure in announcing during the weekend that natural gas service would be shut off to homes in the Portuguese Bend area of the city of Rancho Palos Verdes.

“We regret this unexpected disruption of service,” the company said in a statement. “This dynamic situation requires we take immediate action to protect public safety.”

The land is moving as much a 9 inches (22.8 centimeters) per week, the company said.

The gas company said it will give $2,500 to each account holder to help with immediate needs, such as laundry and meals. There was no estimate for restoration of service.

Portuguese Bend is among several neighborhoods in an area of ancient landslides. Significant increases in land movement began in spring 2023, following heavy winter rains. Water percolating into the ground is believed to be lubricating the earth.

Earlier this year, earth movement forced the dismantling of the landmark Wayfarers Chapel to prevent it from being destroyed. It is hoped that it can be reconstructed elsewhere.
