North Coast User Group (GIS) 2013.10.16

Here is a presentation I gave to the Northcoast User Group at the Wharfinger Bldg. in Eureka.

Here is the digital presentation (103 MB pptx)

Here is the video of turbidites in the lab (2 MB mpeg)

Here is the Cal Tech animation of subduction zone earthquake cycles (4 MB avi)

Here is an older draft of my paper where I discuss my methods and results in greater detail.

Here is today’s schedule:

8:30 – 9:00 Welcome, Introductions, Announcements:
Jerry von Dohlen – NCUG Coordinator,

9:00 – 10:00 “Slope Stability: Factor of Safety along the Seismically Active Continental Slope Offshore Sumatra” By Jason “Jay” R. Patton, Associate Faculty, at College of the Redwoods and Board Member Cascadia GeoSciences.

Slope stability evaluation for seafloor topography along the Sunda subduction offshore Sumatra, Indonesia. Use of sediment material properties, from local (Sumatra) and analogous sites, to constrain estimates of static slope stability Factor of Safety (FOS) analyses. Then the use ground motion prediction equations (GMPE’s) to estimate ground motion intensity (Arias Intensity, AI) and acceleration (Peak Ground Acceleration, PGA), as possibly generated by fault rupture, to constrain seismic loads for pseudostatic slope stability FOS analyses. This method can be used here in Cascadia for submarine and subaerial settings.

10:00 – 11:00 Break and Map Gallery Presentations

Please feel free and bring maps for presentation and open discussion.

11:00 – 12:00 “A Discrete Approach to Vegetation Mapping based on Landsat Imagery for the Development of Quantitative Attributes” By Ken Stumpf, President and Director, of Geographic Resource Solutions.

Presentation of the basic Discrete Classification Mapping Methodology used for the Redwood National Park Vegetation Mapping and Lassen Volcanic National Park projects using examples and results from both projects.

This methodology has been used to develop both pixel and polygon map data sets that include National Vegetation Classification System Alliance/Association level type names, but also include species-specific cover estimates, tree size estimates, and stocking (stems/acre) estimates. Quantitative estimates also include cover by canopy position or layer, mortality, and fine and coarse woody debris counts by fuel and decay classes
