Remember that flooding may occur after a mudflow or a landslide. These type of landslides can be large and damaging and occur where alternating layers of strong and weak rock slope downhill. The direct cost of landslide damage includes the repair of roads and property and the loss of life. USGS research on the North Fork Stillaguamish River is aimed at identifying potential impacts to the aquatic ecosystem and changes to flood risk along the river corridor including newly reconstructed stretches of State Route 530 and downstream bridges. The cause of the slide was determined to be rainfall and melted snow, which saturated the slope. Lynda specializes in coverage of the environment, natural history and Native American tribes. Excess weight, from accumulation of rain or snow, from stockpiling of rock or ore, from waste piles, or from manmade structures, may stress weak slopes to failure. This work entailed making approximately 1,400 on-site observations of the landslide surface to reconstruct the displaced geology of the landslide deposit in order for the mobility of the landslide to be deciphered. Saturation, by snowmelt or heavy rains, that weaken rock or soils on slopes. These spiders, which were placed on and near the landslide, contained high-precision GPS units for detecting landslide movement as well as geophones for detecting small vibrations. These slides typically move slowly over decades, even centuries. These surveys were performed at irregular intervals between July 1, 2014 and July 7, 2015. Your county geologist or county planning department may have specific information on areas vulnerable to landslides. Landslides exist throughout Washington State and can be triggered in many ways.

The principles at work are familiar to anyone who has ever built a sand castle. A 1997 slide on Perkins Lane in the Magnolia neighborhood sent houses tumbling to the beach. This is because water adds significant weight to the slope as it seeps into the ground and becomes groundwater. These are clues that the ground is shifting. Research by the U.S. Geological Survey indicates that the landslides average speed was about 40 mph, with maximum speeds likely even higher. Movement is accompanied by cracking of the ground. A landslide susceptibility map is planned to be released later this year to identify areas where small landslides may happen in the future.
