Natural Hazards on the Island of Hawaii
Skills and concepts that students must have mastered
How the activity is situated in the course
Content/concepts goals for this activity
This jigsaw exercise is designed around the use of four large posters with maps and data about: 1) Lava Flows, 2) Explosive Eruptions, 3) Earthquakes, and 4) Tsunamis. Students will learn to evaluate data sets from these four processes. They will communicate new observations, interpret data to design a hazard zone map, synthesize information from multiple disciplines, and present a summary of their collaborative work.

Description and Teaching Materials
The first four files are the large posters (and suggested printing size) with maps and data to be printed by the instructor to use in the jigsaw exercise.
- Lava-flow-map.pdf (Acrobat (PDF) 7.3MB Sep3 13) (full size: 36 inch width x 36 inch height)
- Explosive-eruptions-map.pdf (Acrobat (PDF) 5MB Sep3 13) (full size: 48 inch width x 36 inch height)
- Earthquakes-map.pdf (Acrobat (PDF) 4.1MB Sep3 13) (full size: 36 inch width x 36 inch height)
- Tsunami-map.pdf (Acrobat (PDF) 15.2MB Sep3 13) (full size: 96 inch width x 36 inch height)
- Hazards-Hawaii-directions.doc (Microsoft Word 47kB Sep7 13) - This is a word document with the student instructions for the jigsaw exercise; 2 pages at 8x11 inch size.
- Topographic-map-Hawaii-8x11.pdf (Acrobat (PDF) 1.5MB Sep7 13) - This is a basemap of the Island of Hawaii for students to use to draw their preliminary and final hazard zone maps on. Two copies are necessary for each student.
- Lava-flow-velocity-exercise.docx (Microsoft Word 2007 (.docx) 1.5MB Sep7 13) - This an exercise and map for the Lava Flow Hazard Specialty group only. One copy (1 page) is required for each student in this group, about one quarter of the class. The map is for students in this group to use to calculate lava flow velocity of several Mauna Loa flows.
- Isopach exercise.doc (Microsoft Word 884kB Sep7 13) - This an exercise and map for the Explosive Eruption Hazard Specialty group only. One copy (2 pages) is required for each student in this group, about one quarter of the class. The map of the Kīlauea summit area is basically the same as the Keanakākoʽi Tephra map on the Explosive-eruptions-map.pdf poster. The map is for students in this group to use to draw isopachs on the map, and then answer the questions for their specialty in the directions.
- Seismic-cross-section-exercise.pdf (Acrobat (PDF) 4.8MB Sep13 13) - This map is for the Earthquake Hazard Specialty group only. One copy (1 page) is required for each student in this group, about one quarter of the class.
Colored pencils or crayons are necessary for drawing the preliminary and final hazard zone maps on the Topographic-map-Hawaii-8x11.pdf.
Blank white 8x11 paper should be available for answering questions in the exercise.
There is no separate exercise for the Tsunami Hazard Specialty Group because the questions in the exercise directions will take time to complete.
