G.I.S. Activity: Mapping Active Volcanoes

At this moment, a volcano somewhere in the world is erupting or is about to erupt. In this map activity, you will use a computerized mapping program called Arcview GIS, to help locate volcanic activity around the world.

Procedure:

Using figure 1.1 “Locations of Volcanic Activity” and Arcview 9.2, you will map current locations of active volcanoes.

1.)  Open arcview 9.2. This is located in your CGF3MI-01 folder on your desktop. You will be creating a new project with a new view.

2.)  To add data click on this button in the menu:

a.  Click on the ‘connect to’ button (File folder with a plus button)

b.  Change your drive to your account on GRCI – xxxx. Go to Data$ (GRC……) (N drive)

Find the GIS Data file - Arcview Data - Esri V9.1 Data – Data&Maps&StreetMaps USA – World – Data and click ok.

c.  Select the following data files to add to your map. Use the control button on your keyboard to multi-select.

i.  latlong.sdc

ii. cntry05.sdc

iii. geogrid.sdc

iv.  lakes.sdc

Click the Add button.

3.)  You now want to make sure that everything is visible on your screen. Make sure that you check off each box in the ‘legend area’ and slide the country layer to the bottom. Double click on the colour in the legend menu to change the colour or any feature (e.g. lakes should be blue). You can also retype the ‘legend’ items to accurately reflect the layer (e.g. cntry05 is Country).

4.)  Add your draw toolbar by going to the menu item Customize – Toolbars – Draw.

5.)  You will be plotting volcanic activity around the globe. To find the location of a volcano

from the chart (Fig. 1.1 below), your latitude and longitude will display in the bottom right corner of the screen; OR you can click on the xy button from the toolbar and enter it manually. Be sure to note that the Latitude and Longitude are revered.

5.)  To insert a triangle symbol like the one in the picture, select the dot drawing feature from the drawing toolbar. Once you have inserted a ‘dot’, double click on it to change the symbol to a triangle. Now you can plot all 20 volcanic locations. You also need to label each, using the text buttons.

6.)  Once you have plotted all 20 locations, use the drawing tool and select the zig zag feature to illustrate all major plate boundaries. This means that you need to draw all of the plate boundaries. Use the map in your textbook or from your notes, to show you the approximate boundaries of each. The following plates need to be indicated.

Eurasian, Pacific, North American, South American, African, Arabian, Indo-Australian, Cocos, Juan de Fuca, Caribbean, Nazca, Philippine,

7.)  You need to label each of the plates as well. Use the textbox in GIS to do this. Label each of the plates indicated on the class map handout.

8.)  Now once complete, go to View - Layout view. This screen takes a snapshot on your main screen. Change your layout to landscape on the File: Page and Print Set-up screen. Resize if needed. From this screen, go to Insert and add a legend, title, border (if needed), and a scale (in kms). You can use your drawing tools to add your volcanoes and plate boundaries symbols to the legend. Please be sure to have a title that states WHEN, WHERE, and WHAT the map is. Underline your title, and add your name and date to the top right corner before printing.

Analysis and Conclusions

1.)  From the 20 volcanoes (that you plotted) create a chart that illustrates which volcanoes are found at the following boundaries.

a.  Converging boundaries (subduction)

b.  Diverging plate boundaries

c.  Hot spots

2.)  a. Once your map is printed, use a yellow marker or highlighter and carefully indicate the location of the Pacific Ring of Fire on your map

b.  Of the volcanoes listed in the table, find the ratio of the number of active volcanoes in the Pacific Ring of Fire to the total number of active volcanoes that you plotted.

c.  Based on your analysis, why do you think so many active volcanoes exist around the ring of fire? Describe what is happening in this area to explain the active volcanism.
