  1. GEOL 108 - Crises of a PlanetLab 4 - Volcanic Hazards and Igneous Rocks • Sept. 23- 28, 2012 Department of Earth Sciences

  2. QUIZ 2 REVIEW Part 1: The January 2010 Haiti earthquake was one of the most destructive in recent history. It measured 7.0 in magnitude. Use the seismogram and travel-time graph to fill in the following chart. REVIEW | 2 Department of Earth Sciences

  3. QUIZ 1 REVIEW • Part 3: What geologic condition in Oregon and Washington indicates the possibility of a Sumatra-like tsunami hitting this coast? How is this related to the mountains and volcanoes onshore called the Cascade Range? (2 points) http://www.tulane.edu/~sanelson/geol204/eqhazards&risks.htm REVIEW | 3 Department of Earth Sciences

  4. LAB 4 - VOLCANIC HAZARDS AND IGNEOUS ROCKS • Assess volcanic hazards in different settings • Read topographic maps • Recognize some igneous rocks and where they form VOLCANIC HAZARDS | 4 Department of Earth Sciences

  5. TOPOGRAPHIC MAPS Scale: 1:250 000 Contour interval 200 ft Sandstone in Canyonlands, Utah • VOLCANIC HAZARDS | 5 Department of Earth Sciences

  6. TOPOGRAPHIC MAPS Scale: 1:24 000 Contour interval 10 ft • VOLCANIC HAZARDS | 6 Department of Earth Sciences

  7. TOPOGRAPHIC MAPS • Topographic contour lines are lines of constant elevation • Hachured lines indicate depressions • Pay attention to contour interval • Relief = elevation difference • VOLCANIC HAZARDS | 7 Department of Earth Sciences
