NASA Radar Imagery Reveals Details About Los Angeles-Area Landslides. Landslides on Palos Verdes peninsula have been moving rapidly in last two years. NASA airborne radar called UAVSAR flies on piloted NASA planes and measures displacements of the ground surface using InSAR analysis. We requested flights in three directions to map motion of landslides on the Palos Verdes peninsula next to Los Angeles. #NASA #NASA_JPL #InSAR #radar #landslides

NASA Jet Propulsion Laboratory (JPL)NASA Radar Imagery Reveals Details About Los Angeles-Area LandslidesAnalysis of data from NASA radar aboard an airplane shows that the decades-old active landslide area on the Palos Verdes Peninsula has expanded.

This is very interesting: mobility of seismically triggered landslides (noisily) increases with size below a certain threshold, but above it mobility decreases with size.

My first (ignorant) hypothesis is that it's some sort of interaction between the seismic wave field and the failure surface...

‘The land is tearing itself apart’: life on a collapsing #Arctic isle

On #Qikiqtaruk, off Canada, researchers at the frontier of #ClimateChange are seeing its rich ecology slide into the sea as #MeltingPermafrost ice leaves little behind

“It’s one thing to think about what the changes mean to us, but I can’t imagine the fear and stress the animals feel as everything changes so fast. We’re supposed to be the guardians of the land. But we’ve let them down.” - Richard Gordon.

By Leyland Cecco, on Herschel Island–Qikiqtaruk
November 21, 2024

"Armed with a fleet of drones and working closely with Indigenous Inuvialuit rangers, the team has revealed a rapid reshaping of the tundra with little precedent. As they race to understand what those changes might mean, a combination of rising seas, landslides and flooding mean the landscape is literally collapsing around them, making it harder to study an island that reflects the tumultuous future of the western Arctic."

“Natural hazards like earthquakes, volcanoes, landslides, and floods impact millions of Americans every year. The U.S. Geological Survey monitors these hazards in realtime, giving communities early warnings and critical information. In some cases, forecasting where the threat is greatest and helping reduce the risk to people, homes, and infrastructure. From earthquake early warning to coastal change forecasting, USGS science saves lives and helps protect the economy. Enhancing the safety and resilience of our country. Making us a more Hazard Ready Nation.”
