A landslide struck the village of Gjerdrum, which is about 25km (15 miles) north-east of the Norwegian capital, Oslo. The slide is already being called a “quick clay” landslide by officials. It occurred around 4 am local time on December 30, 2020, and injured 10 people, one critically, and forced some 700 residents to evacuate. As of December 31, authorities were searching for 10 missing residents. Rescues were only possible by helicopter because of the unstable situation. They are also employing dogs and drones in the search for the missing. The slide measures 300m by 700m (985ft by 2,300ft). Another quick clay landslide occurred near the town of Alta, Norway earlier this year.
A teenage girl strolling on the beach in Pacifica, California was buried alive by a landslide. She was buried up to her chest, and a passer-by dug her out with his bare hands while more soil and rock fell around them. Story at KTVU San Francisco. See a nice oblique aerial photo of the beach prior to the landslide here. Those slopes don’t look particularly stable to me but what do I know?
Amazing video of a rockslide as it happened yesterday along U.S. Highway 64 in the Ocoee River gorge in Tennessee. TDOT crews had almost finished removing rockslide debris from an event earlier in the day when a second slide occurred, blocking the road again. That looks like a pretty planar joint set dipping right into the roadway and everything was wet from the recent rains. Click through for the video.
