Last evening I had the privileged to attend a talk at the Wilsonville Library in Wilsonville, Oregon. The speaker was James Roddey, an employee of the Oregon Department of Geology and Mineral Industries. He is tasked with educating people about what is to come here in the Pacific Northwest.
Through historic information (both written, and verbal tradition), and physical evidence, the pieces of the geological puzzle are assembled. Mr Roddey, begins by giving a history of the seismology, and other activity in the region.
