Earthquake Depth > Step One

To examine earthquakes at different depths we'll need to request a series of maps with earthquakes grouped at the following depths from QUEST:

1. 0-20 km
2. 20-100 km
3. 100-300 km
4. 300-500 km
5. 500-700 km

• 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.

• Next, click on the Menu button in the bottom left corner of the QUEST window.

• Click on Map Area and the map area window will appear.

• Next, select World in the Region pull down menu and click OK to close the window.

• Now, click on Data Sets (on the Menu button) 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.

• Next, you'll select an earthquake depth range. Begin by clicking on the Depth button and using the Minimum and Maximum text boxes to select a depth range. When you are finished click OK button in the blue window and the OK button 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).

• Repeat this process for each depth range listed above.
