Reading the Washington Landscape
Reading the Washington Landscape's Latest Posts
A bit of messing around with some DEM (digital elevation model) and came up with some visuals of the lower Nooksack River in northwest Washington. By shifting the elevations of the colors one can enhance features that would otherwise be hard to see.The first image shows the complicated story of part of the Nooksack River and some late ice age drainage patterns. The dark green is lower elevation. The Nooksack flows towards the west into a broad valley formed by an […]
The GEER report on the Oso slide has been released. http://www.geerassociation.org/GEER_Post%20EQ%20Reports/Oso_WA_2014/index.htmlGEER stands for Geotechnical Extreme Events Reconnaissance. I believe this is the first landslide the program has looked at. They visit sites shortly after huge floods, tsunamis and earthquakes to gather evidence of the event before it weathers away. I utilized a GEER report for assessing scour potential from tsunami in a tsunami inundation area.
I have periodically posted on Whatcom County's long and complex struggles with rural planning and the Growth Management Act - long and wonky and local issues that shape the landscape. Whatcom County is just one county, but being local I know the GMA planning here better than elsewhere. Whatcom County lost on water quality and water quantity issues on appeals before the Growth Hearings Board last year. The County has appealed the Boards rulings on water quality and quantity planning […]
NASA image of Washington State wildfiresThe passage of thunderstorms across the east slopes of the Cascade Range ignited numerous wildfires. Forest fires on the east slope of the Cascades are a common event. In rural residential areas within the dry forests home loss is also not uncommon. I am fairly cognizant of fire hazard areas, but have to admit a bit of surprise at the damage that directly hit Pateros, a town on the Columbia River outside the forest zone and with orchards on the […]
McGary and others (2014) (nature.com/nature/journal) used electric and seismic sensors to produce an image of the subduction slab and magma plume associated with Mount Rainier. Colors are resistivity which reflects the plume nicely as well as the cold blue ocean crust subduction slab. The red dots are recorded seismic events The Nature article requires subscription, but Utah State has a news release that provides some good information about the […]
