Central Washington University - Measurements of tectonic plate motion using GPS in the Pacific Northwest. Includes information about PANGA, the Pacific Northwest Geodetic Array collaborative project.
GPS Time Series - Measurements made with the Global Positioning System are sensitive enough to detect motion of the Earth's tectonic plates.
Ground Beneath, The - ThinkQuest project about plate tectonics and its effects.
MARGINS Program - Seeks to understand the complex interplay of processes that govern continental margin evolution.
PALEOMAP Project - View the Earth in paleogeographic maps as it has changed through time as a result of plate tectonics and continental drift.
Plate Tectonics - Lesson covering the chemical and physical layers of the Earth, historical development of the theory, and descriptions of the location and types of plate boundaries.
Tectonic Plate Motion - Estimating tectonic motion points around the world using satellite laser ranging (SLR).
Tectonic Plates Reconstruction Tool - Online tool that allows you to render geologic maps of the tectonic plates' positions at various points in time. Can be adjusted for specific areas.
UNAVCO Facility: Plate Motion Calculator - Programme designed to calculate tectonic plate motion at any location on Earth using one or more plate motion models.
World Stress Map Project - World Stress Map (WSM) is the global repository for contemporary tectonic stress data from the Earth's crust.
