Draft SO461 Lab, Fall 2008
Lab: Earthquakes at Convergent Margins
We will work in groups on this lab to collect data and figures. You will then write a paper as individual effort, which will be in the correct scientific format with references and figures done according to the department style manual.
For your assigned plate boundary, discuss the following:
Dimensions of the trench (width and depth).
Number, locations, and elevations of the volcanoes shown in the Smithsonian database.
Dip of the Benioff zone, and how deep it extends.
Locations of the different types of earthquakes, both horizontally and vertically.
What is the convergence rate and direction at the boundary?
What is the age of the crust being subducted?
Boundaries:
Andes, including a discussion of any differences at S8, S20, and S29.
Central America, including a discussion of any differences at N12 and N17.
Indonesia, including a discussion of any differences at E97 and E113.
Japan, including a discussion of any differences at N35, N45, and N55.
Mariana Trench, including a discussion of any differences at N10, N15, and N20.
Tonga-Kermadoc Trench, including a discussion of any differences at S10, and S20.

This will count as the third paper for the course. It will be graded for content and format.
The MICRODEM help file has a topic "Subduction zone features" that links to directions on how to display the various features.
