Old Sticks in the Mud: Hazards of Lahars from Mount Rainier Volcano
Patrick Pringle, Centralia College
Volcanic debris flows (lahars) flow long distances, bury and aggrade river valleys, and cause long-term stream disturbances and dramatic landscape changes. Students will evaluate the nature, scale, and history of ...

Hurricanes: Unit Overview
LuAnn Dahlman, NOAA; John McDaris, Carleton College
In this EarthLabs module, students will do hands-on experiments and study hurricanes in satellite imagery and visualizations. They'll also explore over 150 years of storm data to find out when and where these storms occur. If students are studying hurricanes during hurricane season, they can monitor the position and status of storms in real time. Hurricanes can serve as an exciting entry point into understanding everyday weather, or a culminating topic for an Earth system or environmental science unit.

Using Google Earth to measure seacliff erosion rates
Alfred Hochstaedter, Monterey Peninsula College
This lab uses Google Earth to measure the rate of seacliff retreat. It touches upon coastal processes, natural hazards, and coastal management issues. The central focus of the lab is in the Monterey Bay area.

Exploring California's Plate Motion and Deformation with GPS | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
Students analyze data to study the motion of the Pacific and North American tectonic plates. From GPS data, students detect relative motion between the plates in the San Andreas fault zone--with and without earthquakes. To get to that discovery, they use physical models to understand the architecture of GPS, from satellites to sensitive stations on the ground. They learn to interpret time series data collected by stations (in the spreading regime of Iceland), to cast data as horizontal north-south and east-west vectors, and to add those vectors head-to-tail.Students then apply their skills and understanding to data in the context of the strike-slip fault zone of a transform plate boundary. They interpret time series plots from an earthquake in Parkfield, CA to calculate the resulting slip on the fault and (optionally) the earthquake's magnitude.

Volcano Lab - Google Earth
Tamara Misner, Edinboro University of Pennsylvania
Volcano shape is strongly controlled by eruptive style, which in turn is controlled by magma composition and tectonic setting. This lab utilizes Google Earth, which takes students on a virtual field trip, in order ...

Earthquake Seismograms and Spreadsheets
Eileen Herrstrom, University of Illinois at Urbana-Champaign
This activity takes place in a laboratory setting and requires ~1.5-2 hours to complete. Students read and interpret seismograms, determine the epicenter of an earthquake by triangulation, and learn how to enter ...

Measuring Ground Motion with GPS: How GPS Works
Shelley E Olds, EarthScope Consortium
With printouts of typical GPS velocity vectors found near different tectonic boundaries and models of a GPS station, demonstrate how GPS work to measure ground motion.GPS velocity vectors point in the direction that a GPS station moves as the ground it is anchored to moves. The length of a velocity vector corresponds to the rate of motion. GPS velocity vectors thus provide useful information for how Earth's crust deforms in different tectonic settings.

Reasons for the Seasons
Declan De Paor, Old Dominion University; Steve Whitmeyer, James Madison University
Reasons for the seasons (RFTS for short) is an interactive learning resource that leverages the popular Google Earth virtual globe. It is designed to help students and members of the public visualize and understand ...

Converging Tectonic Plates Demonstration
Shelley E Olds, EarthScope Consortium
During this demo, participants use springs and a map of the Pacific Northwest with GPS vectors to investigate the stresses and surface expression of subduction zones, specifically the Juan de Fuca plate diving beneath the North American plate.

Visualizing Relationships with Data: Exploring plate boundaries with Earthquakes, Volcanoes, and GPS Data in the Western U.S. & Alaska | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
Learners use the GPS Velocity Viewer, or the included map packet to visualize relationships between earthquakes, volcanoes, and plate boundaries as a jigsaw activity.
