Getting started with Structure from Motion (SfM) photogrammetry part of Cutting Edge:Enhance Your Teaching:Teaching with Online Field Experiences:Activities
Structure from Motion (SfM) photogrammetry method uses overlapping images to create a 3D point cloud of an object or landscape. It can be applied to everything from fault scarps to landslides to topography. This ...

Converging Tectonic Plates Demonstration part of Geodesy:Activities
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.

Measuring the Inclination and Declination of the Earth's magnetic field with a smartphone part of Cutting Edge:Enhance Your Teaching:Teaching with Online Field Experiences:Activities
The poles of the Earth's magnetic field are not precisely aligned with the geographic north and south poles and, in fact, vary continuously. This activity introduces to students the Earth's magnetic ...

Detecting Cascadia's changing shape with GPS | Lessons on Plate Tectonics part of Geodesy:Activities
Research-grade Global Positioning Systems (GPS) allow students to deduce that Earth's crust is changing shape in measurable ways. From data gathered by EarthScope's Plate Boundary Observatory, students discover that the Pacific Northwest of the United States and coastal British Columbia — the Cascadia region - are geologically active: tectonic plates move and collide; they shift and buckle; continental crust deforms; regions warp; rocks crumple, bend, and will break.
