Determining Earthquake Recurrence Intervals from Trench Logs
Patricia Cashman, University of Nevada-Reno
Trench logs of the San Andreas Fault at Pallett Creek, CA are the data base for a lab or homework assignment that teaches about relative dating, radiometric dating, fault recurrence intervals and the reasons for uncertainty in predicting geologic phenomena. Students are given a trench log that includes several fault strands and dated stratigraphic horizons. They estimate the times of faulting based on bracketing ages of faulted and unfaulted strata. They compile a table with the faulting events from the trench log and additional events recognized in nearby trenches, then calculate maximum, minimum and average earthquake recurrence intervals for the San Andreas Fault in this area. They conclude by making their own prediction for the timing of the next earthquake.
Determining Mantle Temperature and Composition from Discontinuities
Anna Courtier, James Madison University
This pair of activities uses observations of mantle discontinuity structure to examine mantle heterogeneity and differences in the depth extent of melt sources for ridges and "hotspots." The first ...
Finding the Moho under Milwaukee
Vince Cronin, Baylor University
A seismogram was recorded at the University of Wisconsin-Milwaukee by Keith Sverdrup during the explosive demolition of a section of the nearby Hoan Bridge on December 28, 2000. The explosive demolition and ...
Where is that chunk of crust going?
Vince Cronin, Baylor University
I introduce students to GPS, frames of reference, and the permanent GPS stations in the EarthScope Plate Boundary Observatory (PBO) in class, and obtain near-real-time data for two stations from UNAVCO. We use ...
Petrography and Petrogenesis of a Mid-Ocean Ridge Lava Suite
Matthew Smith, University of Florida; Mike Perfit, University of Florida
This activity is designed to accompany a set of thin sections available from the authors. Students investigate mid-ocean ride basalt petrography and relate observed mineralogic changes to relevant phase diagrams ...
Is the New Madrid Seismic Zone at risk for a large earthquake?
Eliza Richardson, Penn State University - University Park
In this lesson we discuss the controversy regarding the extent of seismic risk in the central United States today. We learn how to estimate earthquake recurrence interval using a variety of methods. This lesson ...
When and How Did Continental Crust Form?
Dave Mogk, Montana State University-Bozeman
Many models have been proposed regarding the timing and mechanisms that first formed the continental crust. The purpose of this exercise is to help students explore the question of crustal genesis and evolution ...
Characterizing Plate Boundaries
Bill Hirt, College of the Siskiyous
Students examine maps showing four different types of geologic data along three specific plate boundaries, and document the patterns in the data along each boundary. Next, they compare their observations to the ...
Structural Control of Giant Rock Avalanches in Argentina
Barb Tewksbury, Hamilton College
Students analyze the influence of bedrock structures on the locations of giant rock avalanches in Argentina. Activity is available in two versions: 1) short case example that can be used as an in-class activity or ...
Global Earthquakes: Teaching about Earthquakes with Data and 3D Visualizations
Cara Harwood, University of California-Davis
In this series of visualizations and accompanying activities, students visualize the distribution and magnitude of earthquakes and explore their distribution at plate boundaries. Earthquakes are visualized on a 3D ...
