d. You should select the “Annulus” option. e. You can change the color of the line by double-clicking on the color box (make sure each city’s circle is a different color), and you should set the area to “0% Opacity.” f. You then want to change the region name to the name of the city (in this instance, it is Eureka). g. Once you finish those steps, click the “Draw” button, and you should see a large circle around Eureka. (Google Earth should automatically zoom out so you can see the circle.) h. Congrats! You have successfully created one of the three circles needed to find the epicenter! i. Go into “Saved Regions” (in the window on the left side of the screen) and uncheck “Eureka.” This will make the circle disappear (for now). j. Now, you want to go Elko, NV. Like before, once you fly to Elko, you should not use your mouse to move the Google Earth map. k. You should uncheck the “Setup” box (under Range Rings in the left window in Google Earth). l. You will need to reset the ring program. To do this, you need to right-click on “Setup” (ctrl + click on a Mac) and select Refresh . m. Then, select (check the box next to) Setup, and repeat steps A – I for Elko, NV. n. Repeat steps J – M for Las Vegas, NV. o. Under “Saved Regions” select (check the box) next to Eureka, Elko, and Las Vegas, and you should see all three circles in your Google Earth map. Now that you have all three circles on your Google Earth map, you should find the area where all three circles intersect. This is the epicenter of the earthquake . You should add a placemark at the epicenter of the earthquake. To do this, you will see a row of buttons at the top of the Google Earth window. One of the buttons is a yellow push-pin. Click on the yellow push-pin button to create a Placemark for the epicenter. You should title your Placemark “Epicenter,” write down the latitude and longitude coordinates (look at the bottom of the screen or in the window that opens when you create the placemark, and click “OK”. Now you should take a screenshot of your three intersecting circles and the placemark indicating the location of the Epicenter. You will need to upload your screenshot (5 points). The last question on the assignment online will allow you to do this.

6 To take a screen shot: If you are on a PC: i. With the Google Earth window open (and showing all three circles and the Epicenter location), hit “Ctrl” “Alt” and “PrintScreen” or “PrtSc” simultaneously. ii. Go to “Accessories” à “Paint” and open a new file iii. Go to “Edit” à “Paste” and you will see a picture of your computer screen in Paint. iv. You should save the file as a JPEG, name it “Last Name_First Name_Epicenter,” and upload the JPEG file to Blackboard. If you are on a Mac: i. Go to “Applications” (in the Finder Window) ii. Open “Utilities” iii. Open “Grab” – This will open the “Grab” program.
