February 2010 Chile Earthquake and Tsunami part of Hazards:Events
Centered off the coast near Maule, Chile, this 8.8 magnitude earthquake on February 27, 2010 was one of the strongest earthquakes ever recorded. The massive quake also triggered a tsunami that swept across the Pacific basin.

Exploring California's Plate Motion and Deformation with GPS | Lessons on Plate Tectonics part of Geodesy:Activities
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.

Earthquake Case Study part of Introductory Courses:Activities
Kaatje van der Hoeven Kraft, Whatcom Community College
This activity is a multiple case study analysis of different earthquakes that leads to student interpretation of claims, evidence and prediction/recommendations.

GPS Velocity Viewer part of Geodesy:Resources
EarthScope Consortium
This interactive tool allows users to see GPS/GNSS-measured crustal motions around the globe in a wide range of reference frames. The default view shows horizontal motions in the North American reference frame but users can choose to add vertical motions, earthquakes epicenters, plate boundaries, volcanic centers, or other reference frames. The tool can also be used as an interface to learn GPS/GNSS station names and download time series data.

Visualizing Relationships with Data: Exploring plate boundaries with Earthquakes, Volcanoes, and GPS Data in the Western U.S. & Alaska | Lessons on Plate Tectonics part of Geodesy:Activities
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.

1906 San Francisco Earthquake and Fire Visualizations part of Hazards:Events
The earthquake that struck San Francisco on April 18, 1906 remains one of the strongest and most significant earthquakes in US history. The fire that developed in its aftermath brought the city to its knees. This collection presents links to images, films, panoramas and animations about the earthquake and fire.

How to Classify Volcanoes part of Videos:Video Gallery
This video describes the features geologists use to classify common types of volcanoes. We compare and contrast the features of two types of large volcanoes - shield volcanoes and composite volcanoes. One of these types produces structures that can be larger than Mount Everest while the other represent the majority of dangerous active volcanoes on Earth.We also explain that two other types of smaller volcanic landforms are relatively common and often form in association with their larger brethren. Finally, you can take a simple volcano recognition quiz to try to classify five examples of US volcanoes.

3D View from a Drone | Make a 3D Model From Your Photos part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
Using cameras mounted to drones, students will design and construct an experiment to take enough photos to make a 3-dimensional image of an outcrop or landform in a process called structure from motion (SfM). This activity has both a hands-on component (collecting data with the drone) and a computer-based component (creating the 3-dimensional model).___________________Drones can take photos that can be analyzed later. By planning ahead to have enough overlap between photos, you take those individual photos and make a 3-dimensional image!In this activity, you guide the students to identify an outcrop or landform to study later or over repeat visits. They go through the process to plan, conduct, and analyze an investigation to help answer their science question.The Challenge: Design and conduct an experiment to take enough photos to make a 3-dimensional image of an outcrop or landform, then analyze the image and interpret the resulting 3-d image.For instance they might wish to study a hillside that has been changed from a previous forest fire. How is the hillside starting to shift after rainstorms or snows? Monitoring an area over many months can lead to discoveries about how the erosional processes happen and also provide homeowners, park rangers, planners, and others valuable information to take action to stabilize areas to prevent landslides.
