Mapping shows a slow-moving landslide now blamed for cracked pavement on SR 109 and could lead to the highway possibly collapsing. Water is not only heavy, increasing the driving force of a slope, but it pushes soil grains apart, insinuating its way between the tiniest particles. The Geological Survey inventoried 2,838 landslides throughout King County using new lidar data, raising awareness of a relatively common geologic .

It's unknown how. Typically, of course, this event has effectively disappeared from the news, even in China - I can find no real updates on the recovery operations since the call for improvements in coal . Any change to the Earth's surface that increases the slope (for example, river incision or the removal of material at the base of a slope by humans) or that reduces the friction of a slope (such as the addition of water) can increase the likelihood of a landslide.

The direct cost of landslide damage includes the repair of roads and property and the loss of life. Another USGS study revealed how models can help explain the travel distance and timing of these types of landslides, which, in turn, can help us improve landslide susceptibility maps for such events in the future. The findings of this work will be published in the coming months and are anticipated to help update and develop models that better capture the true behavior of these types of landslides. 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.

Scientists with the U.S. Geological Survey (USGS)continue to supportall of those involved in responding to the event to assess ongoing hazards and identify possible future impacts. The landslide involved a complex sequence of eventsincluding rotation, translation, and flow mechanismsand can be referred to as a debris-avalanche flow. 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. Failure is often caused by liquefaction (when soil is transformed from a solid to a liquid), usually because of an earthquake. An incident of this magnitude was not expected based on previous studies of past events in the area as well as comparison with landslides worldwide of this height, volume and type.
