Part 2: Analyzing Volcano Data
This lesson is designed to help students visualize earth science data with GIS. Students will also use the Internet to acquire the most recent data on volcanoes worldwide. †In this investigation, you will use the Internet to acquire the most recent data on volcanoes worldwide.
The student is able to:
∑ Use the Internet to locate data for recent volcanic activity.
∑ Map data acquired from the Internet.
∑ Compare the pattern of recent volcanic events with the patterns of seismic events in the past.
∑ Identify world regions and cities where human populations face the greatest threat from current seismic events.
1.1. Locate earthquake data on the WWW
You will now follow a different data processing procedure to collect and map volcano data. Go the Weekly Volcanic Activity report produced by the Smithsonian and USGS at: http://www.volcano.si.edu/gvp/reports/usgs
I want you to spend 10 minutes on this web site (ONLY THIS WEB SITE) to learn about different data and activities they present.
Identify two volcanoes in or near the
Please do not move to the next session until I ask you to do so.
Now letís do some analyses.† Once again, bring the main page up:
This web site does not provide the data similar to the one in
the previous activity.† Instead you have
to extract the data yourself.† At the top
of each volcano activity you will find the location coordinate: Use (negative
values for west and south) and record the location and the Summit Elevation in
a new Excel sheet for 20 volcanoes.† Try
to select the locations near
Looking at the data that you just created:
P1. Generate two visualizations based on this data and write a paragraph for each that reflects your observations and conclusions.
P2. Use MATLAB to create a 3-D view of the data where the x axis is used for west and east and y axis for north and south?
