This activity was selected for the On the Cutting Edge Exemplary Teaching Collection

Resources in this top level collection a) must have scored Exemplary or Very Good in all five review categories, and must also rate as “Exemplary” in at least three of the five categories. The five categories included in the peer review process are

  • Scientific Accuracy
  • Alignment of Learning Goals, Activities, and Assessments
  • Pedagogic Effectiveness
  • Robustness (usability and dependability of all components)
  • Completeness of the ActivitySheet web page

This is a student homework exercise designed to familiarize students with earthquake shaking, acceleration, intensity and hazards, including the quantitative measurement of these properties. Students examine quantitative measurements of earthquake hazard from the U.S.G.S. then use these numbers to determine the damage to their homes (or another location) that could be inflicted by a quake with a 500-year recurrence interval (10% probability of exceedence in 50 years). By using students' own homes, they see the impacts of shaking, hazard, and intensity in a more personal, connected way.

This exercise can be used by any one in the United States, but is most apt for those places with high earthquake hazard. It uses the USGS's hazard mapping program's web site that allows anyone to look up earthquake hazard based on zip code, and is available for the entire United States. It also uses a conversion of acceleration to Mercalli intensity from Bolt (1993) and available on-line. Finally, it uses information from the Association of Bay Area Governments (2003) to describe typical damage to buildings of differing types (including different housing styles and ages) from different shaking intensities.

Context for Use

This is a homework for an introductory geohazards course, course but would be appropriate for any introductory level course.
I use this assignment to reinforce and take home (literally) the relationships between acceleration, intensity, and hazard. They should have already seen these terms and measurements of these terms.
It takes about an hour, and requires internet access.

Teaching Notes and Tips

This is typically usable as a self-directed homework. One thing that sometimes confuses students is that some sources give accelerations in a percentage of g and sometimes as a decimal, so I remind them in class to be careful of this. They will need to convert by multiplying or dividing by 100 (i.e. .05 g = 5% g). It is also mentioned in the instructions.

Teaching Materials

Homework on Earthquake Shaking and Damage (Microsoft Word 38kB Feb12 06) The MS word assignment is fully editable and has full student directions, as well as spaces for students to write their short answers. I have them also submit a summary of what they found on a separate sheet of paper.


I grade the return worksheet followed up by test questions to examine if they appropriately link shaking and intensity. For instance, I often ask why, for a given amount of shaking, Mercalli intensities might vary. They should be able to discuss building construction and perhaps hazards other than ground movement.
