SO461 Lab, Spring 2013
Lab: Earthquakes at Convergent Margins
Work in groups of 2 on this lab to collect data and figures.
For the two locations on your assigned plate boundary, fill out the following table and collect graphics to back up your conclusions. Place them in a PowerPoint, which you will brief at next week's lab.
|Trench Dimensions (depth, width)|
|Volcanoes, number and elevations|
|Dip & Depth Benioff Zone|
|Convergence Rate and direction|
|Age Subducting Crust|
|Characteristics of overriding plate|
|Sediment thickness in trench and forearc basin|
|Aleutians,||W155 and W175|
|Andes||S8 and S20|
|S20 and S29.|
|Central America||N12 and N17.|
|Indonesia||E97 and E113|
|Japan||N35 and N45.|
|N45 and N55|
|Mariana Trench||N10 and N15|
|N15 and N20|
