Mapping
Earthquakes > Step One
Display earthquake data from a year
of your choice (between 1964-1994).
- If you don't have a QUEST window
open mouse over the Tools button along the top banner of this
page. Scroll down to Web Tools and click on the Launch QUEST
button.
- After QUEST opens, click on the
Menu button in
the bottom left corner of the QUEST window.
- Next, click
on Map Area and the map area window will appear. Now select
World in the Region pull down menu and click OK to
close the window.
- Now, click on Data Sets and
the Data Sets window will appear in the middle of your QUEST window. Select
EARTHQUAKES from the pull down menu and then choose SELECT
EARTHQUAKE CRITERIA.
- Begin by selecting a time period
of one month from the pull down menus without changing the depth or magnitude
ranges and click OK in both the blue Earthquakes window and OK
in the tan Data Sets window.
- Lastly, click on the GET MAP
button and in a few moments your map will appear in the main map area
(the Get Map text will turn red when your map has been submitted).
- Now, make more maps and increase
the length of time one month at a time. (For each map you'll need to go
to the Earthquakes button and follow the steps listed above)
For example, your first request
might be:
Map 1 01/01/1994 - 01/31/1994, and would be followed by:
Map 2 01/01/1994 - 02/28/1994
Map 3 01/01/1994 - 03/31/1994
Map 4 01/01/1994 - 04/30/1994
Map 5 01/01/1994 - 05/31/1994
Now, take a few minutes to think about the maps that
you just plotted by answering the following questions and turning them in
to your instructor.
1. How many earthquakes occur
in a typical month on a global basis?
2. On average, how many earthquakes occur per day?
3. How many months of data are required for the plate boundaries to
emerge?
