Click on CONTENT in the details header.

  1. This information will tells you what maps are LAYERED on top of each other inorder to give you the finished map. What are the maps that are included in this map content? Emergency shelters, volcanoes, highways, lava flow hazard zones terrain and topography.
  2. Click on the small black triangle next to terrain and topography. What specific terrain and topography maps are used? Terrain = Hillshate.tif, World Topo Map

Click on the KILAUEA Volcano. There will be a pop-up, explore the information that is there to answer the following questions:

  1. Elevation of area 1222 meters, what type of volcano shield volcano, last eruption 1983
  2. Click to “learn more.” This will enlarge the picture and show a caption. What does the caption say? The 1983 Kilauea eruption sends a river of molten rock down the southwest rift zone. This ongoing eruption ranks the most voluminous outpouring of lava from the volcano in 500 years.
  3. Click ”Zoom to.” Explain the topography. An amphitheater of rifts, with large craters that spill towards the ocean.
  4. What does this area rate as far as Lava Flow hazard zones? Extremely High Hazard
  5. Click on the triangle next to “1 of 3.” Click on the picture. What is the name of the national park and how many visitors do they get per year? Hawaii Volcanoes National Park, 2 million visitors per year.
  6. Click on the triangle next to “2 of 3.” Click on the picture. What is pictured here? What year was the picture taken and how did it change the coastline? Pictured is the rift zone of the Kilauea Volcano in the 1983 eruption. This eruption covered the coastline with 550 square miles of new rock on the southeast portion of the Hawaii Island.
  7. If you were to add a population layer to this map, how would it help first responders during a volcanic eruption? This would help them plan potential areas of the island where people would be trapped. It would also help place additional evacuation routes in high population density areas as well as drills and public education incase of an eruption.
