As such, U.S. Geological Survey scientists have identified it as a key geological-hydrological event that can help explain and inform our understanding of the potential effects of landslides in other settings in the United States and worldwide. USGS scientists continue to study the site to gain new insights that only such a significant, though unfortunate, event can reveal. 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.

Data. Other researchers have identified the ages of some of these landslides, which range from 500- to 6,000-years old, but there is still a lack of understanding for the overall recurrence time frame for these types of landslides. Take our slopes, just add water and gravity. The goal of USGS landslide science is to help answer questions such as where, when, and how often landslides occur and how fast and far they might move. Steeper slopes have a greater proportion of downhill force. That there even is such a guide should be taken as fair warning: We all live in and around landslide country. Especially when the above conditions occur, an earthquake may trigger landslides. Erosion by rivers, glaciers, or ocean waves that create over-steepened slopes.

The Washington Military Department offers both state and federal job opportunities. Water also lowers the strength of the material which can make it less able to withstand the force of gravity. Landslide mobility might have been far less if the landslide material had been slightly denser and/or drier. If enough water saturates the soil, it will not hold together on a slope. Slowly developing, widening cracks appear on the ground or on paved areas. Any commuter on the Sounder trains traveling at the base of bluffs along the shore of Puget Sound is all too familiar with these sorts of landslides, which disrupt service on the mud-piled tracks.
