Lateral spreads occur on very low-angle slopes toward a free face such as a cliff or embankment. These occur much more deeply in the subsurface of the earth. If enough water saturates the soil, it will not hold together on a slope. Saturation, by snowmelt or heavy rains, that weaken rock or soils on slopes. When there is a lot of water and the pore fluid pressure is high, the water buoys up the grains and forces them apart. The addition of water to material on a slope can make landslides more common. Astoria got more than 4 inches (10.1 cm) of rain Thursday, breaking a record for rain on that date set in 1914. Consult professionals if you suspect you are on a landslide. Always drain surface runoff away from slopes, fix plumbing leaks that could saturate soil, and plant and protect native ground cover and trees. Pore fluid pressure is the pressure that water exerts on all of the nearby grains. Water also lowers the strength of the material which can make it less able to withstand the force of gravity.

USGS research indicates that the landslide traveled exceptionally far, crossing the entire one-half-mile wide river valley. Landslides are dangerous, unpredictable, and can occur rapidly. The initiation of slides, like flows or rockfalls, is sensitive to steep slopes, the additional weight of water or other loads, and friction along their base. Over the past five years, scientists have examined a long list of factors which led to the landslide, including soil, water, and climatic conditions. Doors or windows stick or jam for the first time. A landslide is blocking the roadway in the 2200. Communities near rivers draining Mount Rainier and Glacier Peak are at greatest risk.
