Late in the morning of March 22, 2014, a huge chunk of land cut loose and roared down a hillside in the Stillaguamish River Valley just east of Oso, Washington, about 60 miles northeast of Seattle. In a matter of minutes, 43 people lost their lives as a wall of mud, sand, clay, water. A new report details the factors leading to the disaster, the hazards that accompany landslides and steps that can be taken to mitigate landslide consequences and risk in the Pacific Northwest, with the aim of preventing future tragedies.
Scientists have shown how earthquakes and storms in the Himalaya can increase the impact of deadly floods in one of Earth's most densely populated areas.
Microplastics, which are particles measuring less than 5 mm, are of increasing concern. They not only become more relevant as other plastic marine litter breaks down into tiny particles, they also interact with species in a range of marine habitats. A new study takes a look at how global climate change and the impact of changing ocean circulation affects the distribution of marine microplastic litter.
Researchers have developed an integrated sediment, wood, and organic carbon budget for North St. Vrain Creek in the semi-arid Colorado Front Range following an extreme flooding event in September of 2013. Erosion of more than 500,000 cubic meters, or up to ~115-years-worth of weathering products, occurred through landsliding and channel erosion during this event.
The striking North Face of the Bernese Alps is the result of a steep rise of rocks from the depths following a collision of two tectonic plates. This steep rise gives new insight into the final stage of mountain building and provides important knowledge with regard to active natural hazards and geothermal energy.
Geoscientists have revisited the 2013 Bingham Canyon landslide with a combined analysis of aerial photos, computer modeling, and seismic data to pick apart the details.
Scientists have helped discover the remnants of a massive undersea landslide on the Great Barrier Reef, approximately 30 times the volume of Uluru.
