Volcano Monitoring with GPS: Westdahl Volcano Alaska
Learners use graphs of GPS position data to determine how the shape of Westdahl Volcano, Alaska is changing. If the flanks of a volcano swell or recede, it is a potential indication of magma movement and changing ...

Exploring Tectonic Motions with GPS
Learners study plate tectonic motions by analyzing Global Positioning System (GPS) data, represented as vectors on a map. By observing changes in vector lengths and directions, learners interpret whether regions are compressing, extending, or sliding past each other. To synthesize their findings, learners identify locations most likely to have earthquakes, and defend their choices by providing evidence based on the tectonic motions from the GPS vector and seismic hazards maps.

World Map of Plate Boundaries
The plate tectonics mapping activity allows students to easily begin to identify basic tectonic processes on a global scale. As students become aware of plate movements, they begin to identify patterns that set the stage for deeper understanding of a very complex topic. The activity uses a simple "Where's Waldo" approach to identify tectonic symbols on a laminated World Plate Tectonic map.

How Do We Know Where an Earthquake Originated?
Students use real seismograms to determine the arrival times for P and S waves and use these times to determine the distance of the seismic station from the earthquake. Seismograms from three stations are provided to determine the epicenter using the S – P (S minus P) method. Because real seismograms contain some "noise" with resultant uncertainty in locating arrival times of P and S waves, this activity promotes appreciation for uncertainties in interpretation of real scientific data.

Base Isolation for Earthquake Resistance
This document includes two activities related to earthquake base isolation. Learners explore earthquake hazards and damage to buildings by constructing model buildings and subjecting the buildings to ground vibration (shaking similar to earthquake vibrations) on a small shake table. Base isolation a powerful tool for earthquake engineering. It is meant to enable a building to survive a potentially devastating seismic impact through a proper initial design or subsequent modifications. The buildings are constructed by two- or three-person learner teams.

Building Shaking —Variations of the BOSS Model
Building Oscillation Seismic Simulation, or BOSS, is an opportunity for learners to explore the phenomenon of resonance for different building heights while performing a scientific experiment that employs mathematical skills. They experience how structures behave dynamically during an earthquake.

Cupcake Geology: Interpreting Core Samples
This activity helps students understand how geoscientists study the Earth below our feet through drilling. Using a large straw as a "drill", students collect samples through different parts of the specially layered cupcake and keep a "log" of the drill core. By defining different colored cake and filling, they can reconstruct what the interior of the cupcake may look like. Students gain an appreciation for the challenges of determining a plausible geologic interpretation with limited data.

Alaska GPS Analysis of Plate Tectonics and Earthquakes
This activity introduces students to high precision GPS as it is used in geoscience research. Students build "gumdrop" GPS units and study data from three Alaska GPS stations from the Plate Boundary Observatory network. They learn how Alaska's south central region is "locked and loading" as the Pacific Plate pushes into North America and builds up energy that will be released in the future in other earthquakes such as the 1964 Alaska earthquake.

Understanding the Age of the Ocean Floor
In part 1, Students will use data collected during DSDP Leg 3 to plot the age of the sea floor at distances away from the Mid-Atlantic Ridge. In part 2, they learn about paleomagnetic evidence and learn about the ...

Investigating Factors That Affect Tsunami Inundation
Learners modify elements of a tsunami wave tank to investigate the affect that near-coast bathymetry (submarine topography) and coastal landforms have on how far a tsunami can travel inland. Damaging tsunami are most commonly produced by subduction zone earthquakes, such as those that occur in Alaska.
