Activity / Problem Set #1: Hawaii and Indonesia
This problem set is designed to help you focus on the relationships between volcanism and plate motion.
Note that there are three parts to the problem set, and all of the figures are located after the problem set
so you will need to explore the entire document in order to answer the questions. No need to print and
hand in the figures, just the first two pages here (with your answers) and the graphs. Be sure to include
your name on the first page!
You will need to hand in the following items:
Part I – a graph and answers to questions below
Part II - a graph and answers to questions below
Part III – a paragraph-long answer
All parts are due before midnight on Thursday February 10 th .
Part I:
What is the relationship between the motion of the Pacific plate and that of the Hawaiian hot spot over
the last 70 million years?
1. Examine the maps of Hawaii that show the entire Emperor Seamount volcanic chain.
2. After reading the information provided, plot in Excel the relationship between volcano age (on
the x-axis) and distance from Kilauea (on the y-axis). You do not need to include the uncertainty
on each measurement as part of the graph.

3. After plotting the data, determine the relative motion of the hot spot and the Pacific plate. In
order to determine that relationship answer the following questions:
a. What is the slope of the line (be sure to include units)?
b. What does the slope represent (physical meaning in geological terms)?
