North Dakota flooding "severe weather" so soon after the catastrophic tropical storm Imelda in SE Texas, inundation in flood plains already saturated ...
I wonder how bad the fracking damage is? Some degree of sinking, likely. Geophysics teaches us that when a natural resource is depleted, structural problems in Earth systems can happen.
Every day the "American" people let Trump get away with his crimes seems to be creating more and more problems for those people; in this capture of radar imagery, obviously more rain on the way for many parts of the midwest.

Muds and silts preserve fossils especially well when they have a little ash to work with. Both volcanic ash and ash from forest fires can make surfaces slick, and especially prone to landslides, mudslides, and avalanches around intense storm activities. Many slide-based geologic events created fossils we have in our fossil record today, preserving the factual records of prehistoric life.
For much of the PNW, landslides and mudslides are a real threat. Much of our geology underlies active ("recently active" by geologic time as in Mt. Saint Helens, for example) volcanoes, which created layers of ash that make especially hazardous conditions.
Have you heard of Oso, the US town in WA that was literally buried alive in 2014?
Topographic maps need updated frequently in areas where rapid sediment deposits happen, such as storm-changed coastlines, or recent slide and subsidence-affected areas.
Ash is not a requirement for slide activity to happen; sometimes a simple saturated ground is essentially the effect of a solid surface.
Erosion is one way tall mountains become smaller. The Appalachians, for example: "These mountain ranges likely once reached elevations similar to those of the Alps and the Rocky Mountains before they were eroded". Add many existing and human-amplified problems (like coal mining) at the tops of these mountains, and the problems compound.
Ecosteader is an indigenous-friendly community to design, build, and innovate "green" or eco-friendly spaces: wildlife-friendly gardens, micro-homesteads, off-grid communities, artwork, and more. We participate in Ecological Democracy by designing and building our local communities around the health of our shared soil which can only be achieved via sustainable practices.
