For this exercise we meet in a computer lab and students access the IRIS Earthquake Browser to download geospatial information of earthquakes. Students use the GEON Integrated Data Viewer (IDV) to explore the location of earthquake zones and their 3-dimensional characteristics. Students compare the earthquake characteristics of subduction zones, mid-oceanic ridges, and transform faults. This leads into a discussion of plate tectonics.

This introductory activity engages learners in the study of earthquake hazards and the risk these hazards pose to humans in the communities in which we live. Learners will compare three maps of Anchorage, AK, depicting spatial information related to seismic hazards to generate questions about the factors that influence shaking intensity and damage to the built environment during earthquakes.

The geologic record demonstrates that our environment has changed over a variety of time scales from seconds to billions of years. This course explores the many ways in which geologic processes control and modify the Earth’s environment and serves as an introduction to Environmental Earth Science Field Course (12.120), which addresses field applications of these principles in the American Southwest.

Earthquakes in western Washington and Oregon are to be expected -- the region lies in the Cascadia Subduction Zone. Offshore, the Juan de Fuca tectonic plate subducts under the North American plate, from northern California to British Columbia. The region, however, also experiences exotic seismicity -- Episodic Tremor and Slip (ETS).In this lesson, your students study seismic and GPS data from the region to recognize a pattern in which unusual tremors--with no surface earthquakes--coincide with jumps of GPS stations. This is ETS. Students model ductile and brittle behavior of the crust with lasagna noodles to understand how properties of materials depend on physical conditions. Finally, they assemble their knowledge of the data and models into an understanding of ETS in subduction zones and its relevance to the millions of residents in Cascadia.

Students conduct a regional seismic hazard analysis of a region of the United States of their choosing*. Using on-line data, they bring together and investigate the interaction of multiple types of data [ground motion (measured by GPS from UNAVCO), historical earthquake data and fault data] to associate rates of deformation and earthquake activity with hazard potential. Students would develop an assessment of seismic hazard potential. This project also introduces the idea of fault loading and qualitative earthquake interaction.

The online geology lab for community college students was developed during two years of forced online synchronous learning brought on by the COVID-19 pandemic. This open educational resource is a cohesive laboratory manual intended for two-year, non-major college students from the New York area. Each lab is accompanied by a Teacher’s Guide and an online answer sheet (formatted for the Blackboard learning management system). A multiple-choice format is used for many questions, making the labs easy to grade.

Geysers and grizzlies and glaciers, oh my. The national parks may be America's best idea, saving the finest parts of the nation for everyone to enjoy forever. What better way to learn about the natural world than to tour the parks with us? We'll explore how the mountains and valleys formed and why they often come with volcanoes and earthquakes. You'll see what really killed the dinosaurs and how we can help save their modern relatives in the parks. With film clips, slide shows, and our geological interpretations of classic rock songs, isn't it time for a road trip?
