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.
The National Geodetic Data Center (NGDC) of NOAA has an online collection of photos of various geologic hazards. Many of the photos are from older sets of 35mm slides that have been digitized. They are free to use provided you credit the photographer and the NGDC as the source. The would be really useful for educators and for powerpoint presentations. The only drawback is that they are in TIF format and some of them could use some retouching. (Photo by University of Colorado, made available by NOAA/NGDC)
