Lab 4  Due Tuesday October 27

1.      Self-run lab: Walk around anywhere—in the city or outside and find five examples of geology, geologic hazards or geologic resources. These can be any combination of things, ranging from bedrock, construction stone, or even modern geologic processes or features (river features, landslides, etc). Be creative. Photographic and/or sketch and describe each. Provide a few details about geologic origin if you can. Write this up using at least one page. Consult a geologic map (in library) or material on reserve in the library if possible.

web search: “chris heg geology” to find online geology maps to help you. (Put cursor on each color to identify geologic unit); or web search: WA Division of Geology

2.       Video assignment due October 27:  Either by going to the Kirk Library at Centralia College and checking out a video or online, watch the Annenberg Earth Revealed video #15, Weathering and soils and #17 on Sedimentary rocks. Either write an informative two paragraphs on each video, or you may use this link to video review form. Directions for watching the videos online appears at the Annenberg link above. It’s easy to do. You just have to provide an email address and password that you use every time you log in.

3.  Seismology lab assignment: Go to the PNSN (Pacific NW Seismic Network) website. 1) Under "Latest PNW Quakes" link, find out how many quakes have occurred during the past 2 weeks (there is a link to a list of quakes under the map). 2) Record the time and date you looked. 3) What was the deepest earthquake?  4) What was the shallowest earthquake  5) Describe the distribution of earthquakes in your own words--are there any patterns or trends? 6) Go the link on Pacific NW hazards to see an "executive summary" of Pacific NW earthquake hazards. This may be a useful link to mark for future reference.  7) Take a few minutes to read Brian Atwater et al's Surviving a tsunami.... a) Does this information apply to Washington and Oregon? Why   b) What should you do if you are in Westport and you feel the shaking of a very large earthquake?
