GLG410/598--Computers in Earth and Space Exploration, Spring, 2009 Assignment 10

Assignment 10: Hazards Maps

Part 1: Seismic hazard analysis for Flagstaff or Tucson area active faults

Perform a similar analysis to find the active faults in the area of Flagstaff or Tucson areas (your choice). Please make an appropriately symbolized map and also present the table of faults.

Part 2: Active faults and Volcanoes for Arizona

As above, find all of the Quaternary units in Arizona, but also find all of the units that have Q and V or v or Qb or Qtb in them. That would be all Quaternary volcanic rocks. Also find all of the units that have T and V or v or Tb in them. That would be all of the Tertiary volcanic rocks. Extract the Arizona outline from the states.shp shapefile that you have. Use the select by location to get all of the faults that are contained in the Arizona outline.

Make a map that has the active faults in Arizona in red, then the Quaternary Volcanic units all in red, the Tertiary volcanic rocks in orange, and then the Quaternary in yellow, all over the shaded relief. Where are the faults that cut Quaternary? Where are the places with the Quaternary volcanism? Where are the places that have Tertiary volcanism? What was the change in loci of volcanism from the Tertiary to the Quaternary?
