NOvember 2013 L earning A ctivity : Mapping Quake Risk Grades 7-12 Today, people are “mapping our world” with the aid of Geographic Information Systems (GIS) technology. Mapping can be done in the field or the lab—even from smartphones. You can make maps with real-time data about wildfires, tsunamis, and tornadoes. You can make maps with imagery collected with visible light, infrared, and radar data. GIS helps people solve everyday problems in Earth science from coastal erosion on the local beach to global climate change. Why? Because Earth science happens everywhere, and analyzing data through maps empowers us to understand our world and make it a better place. In this activity, you’ll use GIS to observe worldwide patterns of earthquakes and volcanoes and analyze the relationships of those patterns to tectonic plate boundaries. Then you’ll identify cities at risk. Materials •Computer with Internet access Procedure Source: Esri. Adapted with permission. Sunday 1. Go online to http://esriurl.com/MOW21map. You’ll see a map with three layers turned on: Earthquake Location, PDC Active Hazards, and Holocene Volcanoes. The check mark next to the layer name tells you the layer is turned on and visible on the map. You can Monday Tuesday use the three-button panel above the layer names to jump between map information, contents, and legend. 2. Turn off the Holocene Volcanoes layer and PDC Active Hazards layer so that only Earthquake Locations are showing on the map. Do earthquakes occur in the Comparing the population density of southeast Asia to earthquakes, volcanoes, and places you expect? plate boundaries in the Our World GIS Education curriculum. 3. Turn on the volcanoes layer. What patterns do actual plate boundaries to the ones you you see in the volcano locations on the map? hypothesized in the previous step’s question. 4. In the Earthquakes layer, each point is Record all similarities and differences. Are symbolized on the map representing its there any areas where physical features, magnitude on the Richter scale.
