Strengths of the Module
- Numerous study areas are included. The module involves case studies from Italy, Peru, Southern and Northern Washington, Alaska, Utah, Upstate New York, Yosemite Valley, and Colorado. The diversity of tectonic, geologic, and climatic regimes in these study areas, as well as the societal impact of each event, provides an excellent opportunity to compare and contrast different mass wasting events. For students who live relatively close to one of the study sites, the module also offers a chance for some place-based learning.
- Students consider the scientific and societal aspects of mass wasting and a variety of data sets. Over the course of the module, students work with topographic maps, slope and aspect maps, Lidar hillshade images, digital elevation models, InSAR data, aerial imagery, and precipitation data to analyze mass wasting hazards. An important part of the module involves a consideration of how existing populations in mass wasting-prone areas would be influenced by a mass wasting event and how anthropogenic factors such as infrastructure and land use contribute to an area's mass wasting susceptibility.
- Activities require qualitative and quantitative analysis to interpret mass wasting hazards. A significant amount of qualitative analysis and synthesis of multiple data sets is required for students to rank particular areas within a study site as having a high, medium, or low mass wasting vulnerability. There are numerous opportunities for students to do quantitative work to characterize an area's mass wasting susceptibility. The Yosemite Valley exercise in Unit 2 involves slope calculations and construction of topographic profiles to compare mass wasting potential in different areas of the valley. In Unit 3, students consider the resisting force and driving force and use trigonometry to make predictions about how the angle and lithology of a hillside influences mass wasting potential. They calculate slide areas and velocities for the 2014 Oso, WA event in Unit 4.
- The adaptability of activities for different class formats makes it feasible for use in both lecture and lab settings.
Great fit for introductory-level classes in:
- environmental science
- Earth system science
- natural hazards
- structural geology
