The USGS has been conducting field work, soils laboratory testing, and additional analyses to identify the likely causes of the large mobility of the Oso landslide. Steeper slopes have a greater proportion of downhill force. This is because the force of gravitywhich acts to move material downhillis usually counteracted by two things: (1) the internal strength of the material, and (2) the friction of the material on the slope. Landslide areas are deemed geologically-hazardous, environmentally-critical areas under the state Growth Management Act. Cracks in walls, bulging walls or cracks in floors. Failure is often caused by liquefaction (when soil is transformed from a solid to a liquid), usually because of an earthquake. During the second stage of movement, the landslide greatly accelerated, crossed the North Fork Stillaguamish River, and mobilized to form a high-speed debris avalanche. My friends at Planet have very kindly acquired a high resolution (SkySat) image of the 22 February 2023 landslide at a coal mine at Alxa League in China .
