A peninsula in L.A. County is slipping at a dissipated charge per unit than before , grant to a NASA analysis of data collected last fall .
The Palos Verdes Peninsula in Southern California has been slip towards the Pacific Ocean for decades . But consort to datum from NASA ’s Uninhabited ethereal Vehicle Synthetic Aperture Radar ( UAVSAR ) , that rate swelled to 4 inches ( 10 centimeters ) per calendar week from mid - September 2024 through mid - October 2024 . Now , the Advanced Rapid Imaging and Analysis squad has produced a visual record the spread and velocity of the landslide , revealing the breathtaking pace of its movement towards the sea .
“ In effect , we ’re seeing that the footprint of land experiencing significant impact has expand , and the speed is more than enough to put human life and infrastructure at risk of exposure , ” said Alexander Handwerger , a landslip scientist at NASA ’s Jet Propulsion Laboratory , in a NASA Earth Observatoryrelease .

The NASA team project UAVSAR data in the figure above , which shows the direction and velocity of the slipping land mass in the area south of the city of Los Angeles . The UAVSAR instrument was go up on a Gulfstream III jet to collect the data , taken over four flight in September and October . The darkest areas in the graphical correspond to the highest fastness .
As indicate in the visual image , active landslides in the sphere have lucubrate beyond the borders of the geologic events set up by the California Geological Survey in 2007 . 100 of buildings in the area now strike within the active landslide expanse .
The landslide coordination compound has been active for at least the past 60 years , according to the NASA Earth Observatory . The enlargement of the coordination compound ’s footprint follows disk - breaking rains in the orbit in 2023 and early 2024 . Those same rainscounterintuitively contributedto the ongoing devastating Los Angeles wildfires , which fed on the winding leafage that brandish in the rainfall and was parched by subsequent droughts .
Handwerger will head up NASA ’s upcomingLandslide Climate Change Experiment , or LACCE , an aerial radio detection and ranging data collection effort that will pore on how uttermost precipitation form — both wet and ironical — influence landslides .
Though landslip - specific , LACCE go hand - in - mitt with theupcoming NISAR planet , a NASA - ISRO ( India ’s space delegacy ) campaign that will observe and map our planet ’s natural processes from depressed - world eye socket . Set to launch in 2025 , NISAR will visualize Earth ’s surface as never before — even 0.4 - inch ( 1 centimetre ) change will be detectable from space .
Taken together , the experiments are aid scientist understand how climate change changes the satellite ’s surface , and how humanity involve to prepare for uttermost weather result .
