Kodiak Quiverings (Revised)
In class assignment (Hand in your map and information sheet) 20 points
Follow the standard protocol for all assignments Grade.
You will need a compass (pencil type) and the map for this assignment.

NOTE: This is partly an IN CLASS assignment. Data will be supplied to complete this assignment to those students who come to class to get it. The seismic data for the assignment will be given out once, in class, if you miss it....you miss it. That's the way earthquakes are "you get one shot at the data in nature, and if you miss it you miss it. The Map for this assignment is available for copy in the library under this class name and KODIAK Assignment.

To complete the questions to this assignment you will find additional information is available on the web at the following addresses: USGS and other links to information on the Good Friday Earthquake (Now known as the Prince William Sound Earthquake) in Alaska of 1964. Search the USGS for information on this earthquake.

Using what you have learned in class, and using the data that you obtained in class you will now determine the epic center of one of the earthquakes (aftershocks) associate with the 1964 Alaska Earthquake. Follow the directions below.

• In this assignment you will have a cover sheet, a map, and an answer sheet.
• The map should include your compass work and show the point of trianglization for the Epicentre of the Earthquake, Identify the point with the letters EC
• The separate answer sheet will contain the data (given in the class) in the format shown below. And this should contain the additional questions and your answers typed on the sheet.
• Make sure you staple the work together

PROCEDURES
Copy the map you find in the library. DO IT FAST other people need it also.

Step 1. Look at the map. This map is an Equal-area map.

Step 2. Look at the data distances you obtained in class. These are distances from the epicenter of the earthquake to each of the stations below. Using the scale at the bottom of the map spread the compass so that it represents the distances from the earthquake determined at each station. Be as accurate as possible. Fine tune the compass if you need to.

Step 3. Using the data and the compass, draw circles around each station at the appropriate distance. Where all the circles meet will be somewhere in the vicinity of of the epicenter of the earthquake. (This is the location on the surface where the earthquake took place. Note: the focus is a point located below this.) Remember, the distance data is calculated on the basis of the arrival times of P and S waves at the various stations listed.

Step 4. Answer the following questions...EXTRACT THESE QUESTIONS TO YOUR word processor and put THESE QUESTIONS on your answers sheet with YOUR ANSWERS. MY grader WILL NOT GRADE THIS IF THESE DIRECTIONS ARE NOT FOLLOWED. STAPLE YOUR MAP ON TOP of your answer sheet WITH YOUR NAME ON BOTH and a cover sheet as the FIRST PAGE. STAPLE. NO STAPLE, NO GRADE. NO COVER SHEET, NO GRADE. NOT TYPED, WITH THE QUESTIONS, NO GRADE.

USE outside resources including your resource skills to answer the following questions:

Question 1. Name the large island near the epicenter of the earthquake. (use an atlas or map of Alaska)

Question 2. Crescent City, CA is the county seat of which, Northern California County? (use an atlas or map of Alaska)

Question 3. Briefly describe:
The type of damage incurred by the Tsunami at coastal cities during and or after the Good Friday earthquake in Alaska and elsewhere along the coast.....especially Oregon.

Question 4:
Comment on the spatial extent of this damage (how far away the impact was felt from the epicenter.
Eye Witness Accounts.

Question 5
Describe the similar roles that liquefaction played in the Loma Prieta event in 1989 and the Good Friday Event in Alaska 1964
Alaska 1964

Question 6
Read the following account. According to this story how was commercial radio stations used or not used as a warning system in the tsunami
approach at Crescent City California
Crescent City Preparations

Question 7
Briefly describe the Mercalli Earthquake Intesity Scale.

Question 8
According to this article what what was the highest extent of Mercalli reading felt in this Earthquake?
